1. Description
"M80SETUP.EXE" contains the 8.0 version of the Logitech mouse
driver for Windows 95, Windows NT 4.0, and Windows 3.1X.
This is a mouse driver update ONLY. The driver works with any
Logitech Serial or PS/2 pointing device(s) operating under
Windows.
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 NT 4.0, please contact Logitech Sales.
Installation of this driver into Windows 3.1, Windows 95, or
Windows NT 4.0 will automatically set the middle button of a
Logitech 3 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) will be
inactive. Install the full retail release of MouseWare 8.0
for full 4 button functionality under Windows 95, 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, Windows NT 4.0
Run M80SETUP.EXE and follow the on-screen instructions to install
this mouse driver update.
3. Features
3.1 Zooming in Windows 95 and NT 4.0
In Windows 95 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 3.1
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
If you have problems operating other serial devices together
with MouseWare, in Windows 95 run Regedit.exe, edit the key:
HKEY_LOCAL_MACHINE\SOFTWARE\Logitech\MouseWare\CurrentVersio
n\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 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, 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
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.
Logitech cannot guarantee that issues resulting from
the incorrect use of Registry Editor can be solved.
