I think I have a lemon...
While working on computer, it tends to have a mind of it's own and starts racing through pictures or where ever I am to the right, very fast. if my cursor is on the toolbar above it will race through the titles until it gets to the far right by the clock and then start thumping like it hit a wall and can not go any further. Purchased the IMac in April and I've had it in once and it started doing it again. Has this ever happened to anyone??
