1. Get the latest drivers from the mouse mftr. and install them.
2. Put new batteries in the mouse.
And make sure the mouse is in range of its base USB dongle.
Plugging a little dongle into the back of the PC's case may
mean the case is screening the signal and putting the
mouse out of range. Using a USB extender putting the
base about a foot from the mouse fixed it for me.
If it's an AA, or worse AAA battery mouse, fresh alkalines
in the mouse may only last a couple of weeks or less.
Rechargeable stands are the way to go, but if the
mouse is off the stand most of the day it too runs
out from not charging enough. I modded mine to
ditch the USB charging, and used a universal multi-voltage
DC wall wart to charge the mouses battery, using AA
2500 Ni-Mh, overnight it charges enough to last all
day. No more mouse problems.
By the way I have a conventional wireless mouse,
Logitech ball mouse, and graphics pad with mouse
and pen/stylus, all move the pointer around.
Being able to reach for the ball mouse with its
horizontal scroll can be very useful for large spreadsheeets.
