I'm using a new iMac 800 with the standard Pro Mouse. Occasionally (probably 5-6 times an hour) the cursor will just skip to somewhere else entirely on the screen. I notice it the most when I'm about to click on a button, scroll bar, etc, and wind up clicking in my dock. I've ruled out: - software conflicts - it's been doing this since day 1, it's just starting to get really obnoxious as i'm doing serious work on the machine - weird pattern under the optical eye - i've tried using no mouse pad (desk is brown fake wood), multicolored mousepad, and plain white mousepad, and it does it under all circumstances Can anyone think of anything else that might work? Has anyone else experienced this?
