I find mice in general have problems, although none as major as my somewhat exagerated post may lead you to think. I had problems with a mouse moving two pixels at a time unless I was logged in as administator (I still don't know why that started or why it cleared up), I've had problems getting the scroll whelel and middle mouse button working in games (I've since found the correct settings) and recently I've had problems with sensitivity halfing randomly, meaning I have to go into the control panel screen and put the mouse senitivity to full - of course, when I switch on my computer the next morning, it's hopelessly over sensitive. This hasn't happened since I attached a second mouse to my system.
No problems with the new drivers so far.
Cheers,
Xain
