--- Comment #52 from Mike Mestnik cheako+winehq@mikemestnik.net 2012-04-17 10:47:29 CDT --- I feel it's important to point out that, for me at least, the mouse pointer's locations were vary predictable and NOT just all over the place:
There was a pattern containing ONLY 4 locations, x(1):y(1) to x(4):y(4) x(1)=x x(2)=x*2 x(3)=x x(4)=x*2
y(1)=y y(2)=y y(3)=y*2 y(4)=y*2
When the mouse is in the upper left corner the 4 locations are vary close together and when the mouse is near the center the 3 other ghost locations are near the bottom and right of the screen. As indicated x(1):y(1) seams to track the 'original'/intended mouse location vary well.
