Mouse spazzing out

Hello

This is a bit of a weird one, and chances are a stupid question but my mouse every no wand again just flips out and has me spinning around lookin at the floor or the celling in games (it also can spaz on desktop, but not as much). It's a relativly old logitach mouse with a 'inferred' light under the base instead of a ball.

are some mouse's un-compatible with vista? or dose anyone else know what can cause this, thanks

Just buy yourself a new mouse..
Sounds like this one had its glory days ... or you are using it on a surface wich makes it responds badly
