Dell 600m....cursor jumping around
I've had this annoying problem on my laptop for quite some time now. I'll be typing and my cursor will just jump to a random spot in the screen. If I do a Ctrl+Z to undo it, then begin typing again, it will often keep jumping around as I begin to type unless I literally stop for a few seconds, then start typing again. It's just incredibly annoying...anyone have any clue at all what could cause this? I'm not hitting any keys and the mouse cursor doesn't do it. It's a problem in the keyboard, what the could make the cursor just jump around like that?
