After many forums, I noticed that there are two specific problems being addressed. One is while typing the curser jumps to another line and continues from there. The other is when the curser jumps up and down the screen to the point you have no control of the curser. It will not respond to any commands except to stop at the hold of the touchpad. This happens for periods of time or until it is rebooted. My biggest problem is the latter. This appears to happen with both Windows XP and Vista on any computer.
