Because of carpal tunnel problems developed over years of drafting, I've used various track ball devices. I'm niow using a Logitch cordless optical TrackMan. It is set up with an acceleration feature so the farther I move the curser, the faster it goes. This way I can get my crosshairs from one side of the screen to the other with a small amount of movement.
My problem is that my track ball settings aren't retained in ACAD 2011. I switch from one from one application to another and my curser moves quickly in each, but when I switch to ACAD, my curser slows down and I need to move my ball much more to get from one spot to another. My ACAD system is set to use the current system pointing device. Is there another setting in ACAD that I'm missing?
