I'm going to keep my suggestion to dump the mouse. There are a number of well documented problems, and although the track pad like control is fun, when things start to go wrong, your love for the beast will diminish fast. Before I quit using mine, it had started to lose its sensitivity, meaning doing most operations at least twice, then it would simply take off on its own, autoscrolling or whatever, then the pointer would simply vanish, then it basically gave up the ghost.
In the end I just don't think you can manufacture something that is this finely sensitive that will hold up to the punishment that a mouse actually takes. Good luck though it's cool while it lasts.
