Mice and Pointing Devices

[Edel]

Im having some trouble with my LX3 mouse, I've had this thing for a while and never had any issues until now. But lately I've had some issues of my middle mouse button not working- something that I use quite often. The scroll wheel still works, and the tilt function works as well. I have tried changing the usb port it was plugged in to, downloaded the latest set point software, and changed the function of the button, but nothing seems to be working. Is there a way to fix this, or is it time to buy a new mouse?
