I installed Win 7 when I got my new motherboard and CPU, it was fine unit when my mouse was kinda like lagging when I was playing game, I first thought it was the game but now I saw it was on the desktop too, I have no clue what happen when I changed to Win 7 I did reinstall the whole computer.
Before I had Win XP 32-bit and on that it worked just fine but when I changed to Win 7 64-bit it just started to do that lag thingy, if I shake it roughly it disappear for a time but it will comeback after a while.
The mouse is Cordless Desktop® MX™ 5500 Revolution I did install the 64-bit Win 7 drivers, It's fully updated, I have reinstall it but it didn't work. I don't think it's the mouse but I will install it to a other computer when I get time to it.
Any help would be appreciated.
