I have a Dell Inspiron 700m, which I love. It has a Synaptics touch pad. Everyone once and a while it freaks out though and acts like someone is holding their finger on a portion of the touch pad so no matter how you move the mouse around, it automatically jumps back when you lift your finger off of it. The older version of the Synaptics software had a “reset device” button that fixed it. The newer version doesn’t though. So I just get to wait for it to go away. Argh.
