Mouse cursor jumping
PC Lenovo M70E, Win 7 x64, active driver 5.7. A problem has recently surfaced where the mouse cursor will be static in the corner of the screen and look like it is juddering. I only appear to be able solve the problem by removing USB from the panel to the PC, and immediately plugging it back in again. Rebooting the PC does not fix the issue, unplugging and plugging back in the mouse (USB optical) does not fix the issue. Any ideas?
