Freaky Mouse Jump

[mikebatho]

I needed to re install OS X the other day...

Now that I have, I have a strange thing going on.....occasionally....

If i leave my machine for a while & come back, wherever I drag my cursor with the mouse, it jumps/skips instantaneously to the far top right corner.

Just the mouse, the cursor control with my Wacom pen is fine...

It's an optical mouse, clean, and there's nothing set in system preferences..

Any suggestions?

I got that when testing a cheap cordless mouse the other day. Our PC in the office wasn't picking up a signal when the receiver was plugged in, but our eMac was, (both are merely for testing purposes). Whenever I moved the mouse, the cursor moved. Great. Whenever I left or right clicked, it moved the cursor into the top corner. So I tried it back on the PC again and it started to work, with both buttons fine too.

Odd.

If it's an Apple Pro mouse, it might be a worn cord next to the mouse casing.

The only time the mouse has jumped like you described, is when I have had the pen resting ontop of the tablet and not in the holder. Other then that, dunno?
