1)I did not install /change anything in between the time when the mouse worked and stopped working
2)The mouse's "ON" LED lights up fine when i plug it into the USB port
3) another mouse works okay.
additional info :
1) running Win XP pro w/SP2
2) not a virus problem
3) It stopped working all of a sudden, no warnings ,popups, etc etc
4) It's a laser mouse (is this any different from an optical mouse? there's no red light like a normal optical mouse but it seems to be able to move the pointer before it stopped working... Also, Is it safe to look at this..."invisible" light without any eye protection?)
5) tried all USB ports on my pc
Thanks for any help
