=====================
Part 1: GENERAL NOTES
=====================

1.1  Installing IntelliPoint software on Windows 95

     When you install the minimum functionality for IntelliPoint 
     software on Windows 95 using Add New Hardware in the Windows 
     Control Panel, you may need to define the path for the 
     IntelliPoint files. For example, when installing from Drive A, 
     you need to define A: as the path.

     To completely install IntelliPoint functionality, you need to 
     run Setup.exe from your product disk.


1.2  Replacing a two-button pointing device with an IntelliMouse or
     IntelliMouse TrackBall pointing device

     When you replace your two-button pointing device with an
     IntelliMouse or IntelliMouse TrackBall, you need to install the
     accompanying IntelliPoint software to enable the wheel and
     wheel button functionality. If you install your IntelliMouse 
     or IntelliMouse TrackBall pointing device without installing 
     the IntelliPoint software, the wheel and wheel button may not 
     work.

     NOTE: When you replace your two-button pointing device with an 
     IntelliMouse or IntelliMouse TrackBall, you may not see a 
     message informing you of new hardware installed when you restart 
     your computer.

     >>>To fix this problem:

     1  Click the Start button, point to Settings, and then click
        Control Panel.
     2  Double-click System, click the Device Manager tab, and then 
        click Mouse.
     3  Select the serial device, for example Standard Serial Mouse, 
        and then click Remove.
     4  Restart your computer.
     
     If your computer does not detect your IntelliMouse or 
     IntelliMouse TrackBall after restarting, try running Setup.exe 
     on your product disk.


1.3  Using CorelDRAW 6.00.112 with IntelliPoint software

     If you use CorelDRAW version 6.00.112 with IntelliPoint software, 
     you may get a general protection fault when you open CorelDRAW. 
     Until you receive your upgrade to CorelDRAW version 6.00.167 or 
     later, you can temporarily fix this error by disabling 
     Point32.exe while using CorelDRAW.

     To disable Point32.exe, do one of the following:

     * In Windows 95, press Ctrl+Alt+Del to display the Close 
       Program dialog box. Select Point32, and then click End Task.

     * In Windows NT 4.0, press Ctrl+Alt+Del, then click the Task 
       Manager button. In the Task Manager, select Point32, and then
       click End Task.
    
     * In Windows NT 3.51, use File Manager to rename the 
       file Point32.exe to another name, and then restart your 
       computer. Click OK when Windows informs you that a program 
       listed on the run line is not available. Remember to restore 
       the original name once you upgrade CorelDRAW.


1.4  Using the wheel in windows with multiple scroll bars

     Windows that contain frames can have multiple scroll bars that 
     may require you to click the content within the window to 
     activate scrolling with the wheel. A frame is a separate, 
     scrolling area within the window.

     For example, when using Microsoft Internet Explorer, if your
     window contains multiple frames with scroll bars, you may need 
     to click the content of the window to activate scrolling with 
     the wheel.


1.5  Using the wheel with Packard Bell's Media Controller

     The wheel and wheel button do not function properly with 
     Packard Bell's Media Controller. If you have problems with 
     Packard Bell's Media Controller, connect your IntelliMouse or
     IntelliMouse TrackBall to the mouse port on the back of your 
     computer.


1.6  Using the PS/2 port on your laptop computer

     Many laptop computers have an internal (PS/2) pointing device 
     (IPD) that may cause your IntelliMouse or IntelliMouse TrackBall
     to work improperly when attached to the PS/2 port. The problem 
     is most likely because both the IPD and your IntelliMouse or 
     IntelliMouse TrackBall are trying to use the PS/2 port at the 
     same time.

     To fix this problem, try one of the following:

     * Disable the IPD or Simultaneous mode, using the BIOS setup
       program. Not all laptop computers have this feature. See your
       laptop computer documentation to change settings with your
       BIOS setup program.
     * Connect your pointing device to the serial port.


1.7  Using a BIOS setup program to enable your mouse port

     If you enable your mouse port (PS/2 port) using a BIOS setup
     program, your computer will detect a PS/2 device when you use
     Add New Hardware, even without a PS/2 device connected. When your 
     computer detects a nonexistent pointing device, you will see an 
     exclamation point beside the PS/2 Mouse icon.

     >>>To display the PS/2 Mouse icon:

     1  Click the Start button, point to Settings, and then click 
        Control Panel.
     2  Double-click System, click the Device Manager tab, and then 
        click Mouse.

     To fix this problem, do not enable your mouse port using your
     BIOS setup program.


==================================
Part 2: NOTES FOR WINDOWS NT USERS
==================================

2.1  Installing Windows NT 4.0 when IntelliPoint software is installed

     If you upgrade to Windows NT 4.0 from Windows NT 3.5x with 
     IntelliPoint, the Windows NT 4.0 default Mouse Properties 
     software replaces the IntelliPoint software. Although 
     Windows NT 4.0 works with the IntelliMouse and IntelliMouse
     TrackBall, not all of the IntelliPoint features are available 
     with the Windows NT 4.0 Mouse Properties software. To have
     access to all of the IntelliPoint features, reinstall the
     IntelliPoint software.


2.2  Installing IntelliPoint software requires system-administrator 
     security privileges

     You need system-administrator security privileges to install 
     IntelliPoint software on Windows NT systems. For information on
     system-administrator security, see your Windows NT documentation.


2.3  Installing IntelliType software

     In Windows NT 3.51 only, if you lose the wheel and wheel button
     functionality after installing IntelliType 1.1 software 
     (available with the Microsoft Natural Keyboard), simply 
     run Setup to reinstall the IntelliPoint 2.1 software, which 
     updates the files needed to work with your IntelliMouse or 
     IntelliMouse TrackBall.


2.4  Attaching multiple pointing devices in Windows NT

     If you attach both an IntelliMouse pointing device and a second
     mouse of a different type (such as a Microsoft Mouse without
     a wheel), you may encounter the following problems:

     *  If you reset the right button to be the primary button using
        the Button Selection feature on the Basics tab in IntelliPoint,
        the second mouse does not recognize the change.

     *  You cannot use the second mouse to set Orientation on the
        Productivity tab in IntelliPoint, and the second mouse does
        not recognize any changes you make using the Orientation
        feature. 

     *  In Windows NT 3.51 only, the wheel and wheel button on the
        IntelliMouse pointing device do not function.

     NOTE:  This does not apply to an external mouse attached to a
     laptop with an internal pointing device.


2.5  Using an IntelliMouse TrackBall or a dedicated PS/2 IntelliMouse 
     on Windows NT 4.0 Service Pack 3

     If you do not install IntelliPoint software on Windows NT 4.0 
     Service Pack 3, you cannot use the wheel or wheel button on an 
     IntelliMouse TrackBall or a dedicated PS/2 IntelliMouse. You 
     may have a dedicated PS/2 IntelliMouse if you purchased it 
     from an OEM.

     To fix this problem, install IntelliPoint software.


2.6  Using a Cybex AutoBoot 4xP switch

     When using a Cybex AutoBoot 4xP switch with your IntelliMouse
     or IntelliMouse TrackBall, your pointing device may have problems 
     working with attached computers. The Cybex AutoBoot 4xP attempts 
     to detect the pointing device, but results in erratic operation.

     To fix the problem on Windows NT, do one of the following:

     * Upgrade the XPLU/LCI firmware to revision C02 (or higher)
       and XPAC/XPAB firmware to revision C04 (or higher).
     * Disable the wheel using the Registry Editor.

        CAUTION

        Incorrect use of the Registry Editor can cause serious 
        problems that may require reinstallation of Windows NT. Read 
        "Changing Keys and Values" within the Registry Editor online 
        Help for instructions on how to edit with the registry. Use 
        the Registry Editor at your own risk.

     >>>To disable the wheel with the Registry Editor:

     1  Create an Emergency Repair Disk using the Repair Disk
        utility, rdisk.exe, located in the \WinNT\system32 folder. 
     2  Click the Start button, click Run, type REGEDT32 in the
        Open field, and then press Enter.
     3  In the Registry Editor, open HKEY_LOCAL_MACHINE, open System,
        open CurrentControlSet, open Services, open i8042prt, and then
        click Parameters.
     4  In the right window, double-click EnableWheelDetection.
     5  Type 0 in the Value data field, and then click OK.
     6  Close the Registry Editor.
     7  Restart your computer.


2.7  Panning in Windows Explorer is disabled in Windows NT 4.0

     Windows NT 4.0 includes scrolling, but does not include panning; 
     therefore, you cannot use the IntelliPoint panning feature with 
     Windows Explorer in Windows NT 4.0. Panning enables users to 
     click and hold the wheel button to scroll through the window.


2.8  Driver or service fails to start in Windows NT 3.51 or later

     When you install IntelliPoint software and then restart your 
     computer, you may receive a message saying that a driver or 
     service failed to start. This message is caused by the system 
     trying to find all of the devices on each PS/2 or serial port. 
     Receiving this message does not affect the performance of your 
     pointing device. 

     >>>To fix this problem:

     1  Click the Start button, point to Settings, and then click 
        Control Panel.
     2  Double-click Devices.
     3  Select the mouse port not in use, mssermou, and click Startup.
     4  Select Disabled, and then click OK.
     5  Close all applications and restart your computer.

     NOTE: Disabling mssermou will prevent your computer from 
     automatically detecting a serial mouse if you connect one to
     your computer.


2.9  Using the wheel with PointCast Network software in Windows NT 4.0

     If you install PointCast Network software after installing
     IntelliPoint software, you may experience problems with the
     wheel functionality. Installing PointCast Network software
     after installing IntelliPoint software disables the Double-Click
     and Help (F1) features if you assigned them to the wheel.

     To fix this problem, upgrade to the latest version of PointCast, 
     which is a 32-bit version.


2.10 Preventing serial device warnings in your Event Viewer

     When you use a Microsoft Mouse, IntelliMouse, or 
     IntelliMouse TrackBall in Windows NT 3.51 or later, without 
     a second serial device installed, you may receive an entry 
     in the Event Viewer for mssermou each time you start your 
     computer. This entry is only a warning that no serial device 
     was detected and does not affect the use of your IntelliMouse 
     or IntelliMouse TrackBall.

     >>>To see if you have mssermou warnings in your Event Viewer:

     1  Click the Start button, point to Programs, point to 
        Administrative Tools (Common), and then click Event Viewer.
     2  Scroll down to locate mssermou entries.

     >>>To prevent mssermou warnings in your Event Viewer:

     1  Click the Start button, point to Settings, and then click 
        Control Panel.
     2  Double-click Devices.
     3  Select mssermou, and click Startup.
     4  Select Disabled, and then click OK.
     5  Close all applications and restart your computer.

     NOTE: Disabling mssermou will prevent your computer from 
     automatically detecting a serial mouse if you connect 
     one to your computer.
