1. Description

   "M82SETUP.EXE" contains the 8.20 version of the Logitech mouse 
   driver for Windows 95/98, Windows NT 4.0, and Windows 3.1X.  

   This is a mouse driver update ONLY.  The driver works with any 
   Logitech Serial, PS/2, or USB pointing device(s) operating under 
   Windows.  Note: USB support only under Windows 98.  

   This release DOES NOT include the Enhanced Mouse Control Center 
   with button assignments.

   For a full retail release of the Logitech Enhanced MouseWare 
   software for Windows 95/98, Windows NT 4.0 or Windows 3.1x,
   please contact Logitech Sales.

   Installation of this driver into Windows 95/98, Windows3.1x,
   or Windows NT 4.0 will automatically set the middle button of a 
   Logitech 3/4 button mouse to function as a left mouse button 
   double-click.  

   If you are using a Logitech 4 button roller mouse or a 4 button 
   mouse or trackball, the fourth button (Thumb button) may be 
   inactive.  Install the full retail release of MouseWare 8.x 
   for full 4 button functionality under Windows 95/98, and 
   Windows NT 4.0.

   Windows NT 4.0 Notes

   NOTE: To install the driver under Windows NT 4.0, you must have
   sufficient access rights to install device drivers.  Log on as 
   Administrator, or contact your System Administrator if you 
   cannot install the driver.

   This release DOES NOT support the Logitech Bus Mouse.

2.   Installation
  
  Before installing any software under Windows NT 4.0, we
  strongly recommend you create an Emergency Repair Disk using
  the Repair Disk utility provided by the system (RDISK.EXE).
  
  
2.1  Standard Installation
  
  Windows 3.1, Windows 95/98, Windows NT 4.0

  Run M82SETUP.EXE and follow the on-screen instructions to install 
  this mouse driver update.
  
3.   Features
  
3.1  Zooming in Windows 98 and NT 4.0
  
  In Windows 98 and Windows NT 4.0, some applications, such as
  Office97, support zooming. To zoom in such applications,
  press the [Ctrl] key and roll your mouse's wheel (if any).
  Be sure your application is Office 97 compliant and supports 
  the zoom function.

4.   Troubleshooting
  
4.1  Detection Problems with PS/2 Pointing Devices
  
  If your mouse is connected to the mouse port and is not
  detected by the system, attempt the following step(s):
    
  1) Your mouse port might need to be enabled through the SETUP
     menu of your computer. Please check your computer
     documentation regarding the SETUP menu. This menu is normally
     accessed by pressing some key, such as F10 or DEL, during 
     system start-up.
  
  2) If you have a mouse with both serial and mouse port
     adapters, connect the mouse to the computer through the
     serial port. Reboot and check if the mouse is detected
     properly.
  
  3) If adapter(s) were not included in your package, your mouse
     was designed to work on only one type of port (Serial OR
     PS/2). Refer to your package for the type of port your mouse
     supports.
  
  If the problem persists, please check for a possible computer
  BIOS ROM upgrade from your computer manufacturer.
  
  Some notebook systems have both an external Mouse Port and an 
  integrated pointing device (stick, touchpad, or trackball) which 
  is connected to the Mouse Port. If your mouse is having difficulty
  running on the Mouse Port of this type of system, try using the
  serial port instead.  


4.2  Serial Port Detection Problems with Serial Pointing Devices
     under DOS and Windows 3.1x
  
  If your mouse is connected to the serial port and is not
  detected by the system, add the following modification to the
  MOUSEDRV.INI file and reboot:
  
  [Technical]
  Timing=Hardware
  
  or load the DOS driver with the following parameter
  MOUSE.EXE NOINI
  
  
4.3  Conflicts with other Serial Devices
  
  1) Windows 95/98
     If you have problems operating other serial devices together
     with MouseWare, in Windows 95/98 run Regedit.exe, edit the 
     key: HKEY_LOCAL_MACHINE\SOFTWARE\Logitech\MouseWare\
     CurrentVersion\Global\PortSearchOrder and remove the unused
     COM ports.
  
  2) Windows NT 4.0
     If you have problems operating other serial devices together
     with MouseWare, in Windows NT 4.0 run Regedit.exe, edit the
     key:
     HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\lsermou
     s\Parameters\Global\PortSearchOrder and remove the unused
     COM ports.
  
  3) Windows 3.1x and DOS
     In Windows 3.1 edit the parameter "PortSearchOrder" in the
     [Global] section of the file MOUSEDRV.INI located in the
     C:\MOUSE directory and remove the unused COM port.

4.4  Power Management Problems

  If your mouse freezes when waking your PC up from suspend, in
  Windows 95/98 run Regedit.exe and edit the key:
  HKEY_LOCAL_MACHINE\SOFTWARE\Logitech\MouseWare\CurrentVersion\T
  echnical\APMMode="Off"
  
  In Windows 3.1 edit the parameter "APMMode" in the [Technical]
  section of the file MOUSEDRV.INI

4.5  How to disable the Middle Button Double-Click

   Under Windows 95/98, Windows NT 4.0, and Windows 3.1x
   some programs require the middle button to generate a 
   standard middle button event, instead of a Double-Click 
   (i.e. like in a CAD or Gaming application).  If you are 
   not running a Logitech Enhanced Mouse Control Center to 
   control the Button Assignments of the pointing device, 
   you may need to disable the default Double-Click setting 
   of the driver and regain a standard middle mouse button 
   click.  To do this, you will need to make the following 
   modification in the Windows Registry (for Windows 95 and
   Windows NT 4.0), or for Windows 3.1x, modify the 
   MOUSEDRV.INI. Follow the instructions below:

   WINDOWS 95/98

   NOTE: For information about how to edit the registry, view the 
         "Changing Keys And Values" on line Help topic in the 
         Registry Editor (REGEDIT.EXE).  Make a backup copy of 
         the registry files (SYSTEM.DAT and USER.DAT) before 
         you edit the registry.

   WARNING: Using the Registry Editor incorrectly may cause 
            symptoms requiring a reinstallation of Windows 95/98.  
            Logitech cannot guarantee that issues resulting from 
            the incorrect use of Registry Editor can be solved.  
            Use the Registry Editor at your own discretion.  
            The Registry Editor should only be used to make the 
            following modifications.  Please follow the 
            instructions below:

   1. Click on the "Start" button on the Windows 95/98 taskbar

      Windows 95/98.

      The middle button should now generate a standard middle 
      button event.

     To disable the middel button double-click, edit the 
     C:\MOUSE\MOUSEDRV.INI file as shown below.

     Under [Global] in brackets you will find a ActiveMouse=
     line. For example if ActiveMouse=MouseMan2, then scroll
     down to the section in brackets called [MouseMan2] as shown
     below: 

          [MouseMan2]
          DoubleClick=001

     Change this line to read:

          [MouseMan2]
          DoubleClick=000

     Note: [MouseMan2] is used for this example only. Your Device
           Model may be different.

     Save your changes and restart Windows 3.1X. The middle button 
     should now generate a standard middle button event.
