Sometimes and this only happens when I'm gaming the mouse will appear to disable and not work and then a few seconds later it will re-enable. During the game I can hear the Windows audio beep that you get when you plug in a USB device. This doesn't happen all the time but has cropped up on a few occasions lately across different games. Any ideas why this might be happening? Could it be mouse drivers? I'm using an Alienware TactX mouse on Windows 7. Cheers.
