a mates computer that is runing xp and a logitech optical wheel mouse is getting what i would call lag or irratic tracking while in windows. the thing is if the pc is doing somthing(processing) the lag dissapears only lags when xp is idle, have tried different brand mice and different drivers but it still has the problem. if the usb controller is deleted in the hardware menu the problem also dissapears until xp is restarted then the problem returns. these are the system specs if they help! gigabyte ga-6vtxd mobo dual p3 1gig cpu's 370 meg ram 64 meg geforce2mx s/b live value 10/100 network card anyone run into a problem like this any help would be appreciated.
