my optical wanders at times... but that could be the bass moving it....

best solution for that mouse is a BFH, then go out and get an optical mouse, they aren't that expensive to pick up either.

lol....but in the meantime....flip it over, twist off the bottom panel, (don't lose the ball though!). You'll see three rollers....they're just plastic shafts....dirt/crap will get on them....I pick it off with my fingernails...but in the event you don't have ones long enough...use a toothpick or q-tip...try not to let the dirt fall back down into the mouse....(blow it out if necessary)....

It may not be the best way to do....but it works....

oh yea....put the ball back in....twist the panel back on....wha-La!

my cat will move my. She likes watch it move across the screen, kind of werid.

it could just be the type of surface its on, if its a ball mouse it should either be on a mousepad or some other kind of surface that isnt too smooth so the ball can actually grip, if its an optical, its best to have it on a smooth evenly colored surface, my optical is on a wooden desk and the grain of the wood is enough to confuse it at times

good point about the surface....but if it is a ball mouse....he'* had it for a year....it'* probably just dirty...

Actually it is better to have some kind of pattern for the optical to pick up and use as contrast while moving. It needs the different variations in color/pattern so it moves better.
