I have a nice MS Laser Mouse 5000 (and matching wireless keyboard). Sometimes, the mouse gets unresponsive. It acts like a dirty ball-mouse but also the buttons stop working properly.
It's only about 2 feet from the wireless hub unit, the reception is shown as excellent, and no battery warning is being seen.
Any ideas? Faulty unit or something I can fix? I've no idea at all what the warranty period is, it's probably just coming up for 1 year old.
