I learned the hard way to never ever buy Microsoft mice, looks like your about to too.
The mouse i have (wireless mobile mouse 6000) is terrible, the wireless lags A LOT, significant dropouts in connectivity, and i had to buy two because the usb connector for the first one literally burnt out after one day of use (2 hours actual, about 6 plugged in but turned off)
Always go Logitech IMO
I know this doesn't help fix your problem but its a warning for everyone else.
Judging my the fact that its a Microsoft mouse, I would say there is no known fix for you problem. Microsoft doesnt care, as long aas they get the money, they are happy.
