Hmm well if you are getting the same effect on either button (but only when switching the button functions), that suggests a driver or possibly an OS issue. A new mouse may or may not fix the problem.

Any computer store or big-box will have lots of good mousies for good pricies.

I'm still using the mouse I picked up back when Circuit City was still in business. Five buttons, built in charging cradle, all for #25. Unfortunately they don't seem to be made anymore, but there are lots of good deals here, of course:

What's worrying me now is I'm starting to get the occasional cursor jumps as well.

Circuit City. A blast from the past, like Comp USA and Computer City.:cool::cool:

I'll likely go to Frys.

Your mouse seems to have elements of some hypochondriac tensile, :D

Plus, it don't work good. :D:D

refrain from alcohol when using your mouse. :O:

Bought a Logitech MX518 optical mouse today and installed it. Everything is back to normal. :cool:

Guess I'll take the old mouse out back and shoot it.

Video! - or it didn't happen! http://i189.photobucket.com/albums/z...trampoline.gif

A still picture is all I can manage. Guess I'll be calling the taxidermy man with a very small job.

BTW I noticed the computer mice in the store today didn't have fur. What's up with that?
