Sinead said, My mother has PD and can't use a PC because she has difficulty using the mouse I use a track ball type mouse. That pesky little arrow, with a regular mouse in my hand, can wind up on the kitchen window, and since I can't find a way to put icons on the window, I went to trackball with lots of adjustment for speed, fixing on target places, etc. It was from Microsoft. Mostly, however, I use laptop (Toshiba) with the little stick in the middle of the keyboard, and this is much easier for me as I have a few fingers that don't quiver, plus the little stick has enough resistance that it doesn't jerk the arrow around too much.
