I have the same mouse.

I wish I could help you Joe, as I have problems of my own.

* Mouse cursor randomly jumps to the start button - in MOHAA this results in looking straight down and spinning in circles until I move the mouse back up
* Thumb button doesn't work in MOHAA - I wanted to use it as my TeamSpeak transmit key (mapped ALT to thumb button and had ALT as my transmit key in TS)

Is there any relation between our problems?
