I just got a new Dell Mini 10v yesterday with Windows XP. When I'm moving the mouse cursor on the touchpad, roughly 10% of the time the cursor will randomly jump up and to the right several inches. With about the same frequency, clicking the left touchpad button will cause the mouse cursor to randomly jump down and to the left several inches. I went to the dell web site and downloaded and installed the latest mini 10v touchpad driver but it made no difference. I've got all the scrolling, tapping, and gesturing options disabled. Is this a driver issue or is my touchpad defective?
