It's a nuisance when blogging, and an real hazard during time-dependent games. A quick Google shows a variety of remedies for cursors jumping while typing, but my problem arises not with the flashing typing cursor, but with the mouse arrow; when I try to move it to a location, it sometimes teleports to a different part of the screen. I've tried replacing the batteries, without improvement.
I'm using a Magic Mouse on an iMac, tracking on a rubberized pad. My three relevant Preferences (tracing, scrolling, double-click) are set on the fastest level. I'm guessing this has something to do with static electricity, but perhaps the optical sensing apparatus of the mouse is wearing out.
Any suggestions would be appreciated.
