I got an equally weird problem with my mouse/cursor... sometimes my pointer will crab sideways across the screen without me touching the mouse... all by itself, like.
The mouse is a cordless Logitech... and no, there are no other cordless mice/mouses within cooee/nearby to cause interference.
maybe I should get one of those computer catz.....
Yeah, mee too... just in case I got one o' them pesky varmints in the machine.
