I've had this wmo 1.1a for quite awhile (I got it from school) and it seems that every time I plug it in the pointer speed is really slow even on 6/11. I have to increase the windows pointer settings to 8/11 or above to make it feel fast. I have it clocked to 500hz with markC fix. Idk if its the mouse or something else. Any other wmo users ever have this problem?
