I'd hate to fool with my own mouse this way, but...

(a) Boot to Safe Mode.
(Hold F5 as you boot, or hold CTRL for the Startup Menu.
Alternatively, turn on the Startup Menu at "START, Run, MSConfig,
Advanced button.)

(b) "Control Panel, System, Device Manager tab".

(c) Open the Mouse branch, & Remove every Mouse driver in it.
If there were more than one (& just one is plugged in), you had a
"ghost".

(d) Reboot to Windows Normal Mode.

If it does not automatically detect the mouse at that reboot, you will
need to reinstall it the way you originally did.

CAVEAT: I have a "Readme" that says (speaking of a Device Manager remove
of the mouse)...

.......Quote..............
Windows 9x and Windows NT 4.0 have the ability to load device
drivers without running the Setup program. Loading the devices
drivers this way, however, does not install the user interface
programs such as the Logitech Enhanced Mouse Control Center.
Using the "Have Disk" function will install only the Logitech
mouse drivers.
.......End of quote.....
