first of all, tell us (the supergeeks
), what kind of mouse it is.. oh, and maybe the place where you downloaded the drivers from, so we will be able to check it.
also, enter http://housecall.antivirus.com/housecall/start_corp.asp
and check lively for viruses.
and one last thing you can do for now is, go to desktop -> right click on my computer -> properties -> device manager -> and check if there is some kind of a light fixture or a yellow exclamation mark.. if there is, what is written near it?
