Yes, that has been my main problem with acceleration, I have never been able to set it to be able to move consistently across the screen in both wide swaths and with precision. Partial work around: using a trackball. The ball has momentum, so I can give it a spin and it will continue to roll. However, this brings up a new issue. Trackballs make mousing in relatively straight lines much more difficult, make image editing a real PITA.<p>Really, most of the screen real estate is completely uninteresting from the perspective of the mouse. Contextual gestures, where sliding the mouse changes the selected control point, I think has potential.
