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, Windows 3.1x, 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) will be set to function as a standard middle button. Install the full retail release of MouseWare 8.x or above 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 M84SETUP.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 95/98 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.

Windows 3.1x 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.
