I have an optical microsoft intellimouse, its an older model, it had been working fine, but last few days it seems to be freezing up very often, which seems strange, i never have anything major running, it does it alot, mouse is about 1.5-2 years old, not sure, i think more around 2 however, could it just be going bad, dont wanna have to spend another 30 on a new mouse, anyone have an idea what it could be, stats are in my sig
