For some reason my mousepad is acting erratic. The mouse won't move and instead the words and icons, and anything else in sight, will be zoomed in and out. If I click the right button down the mouse will move up and down though. Sometimes if I struggle and rub it incredibly hard it will move. Finally, if I restart the computer the mouse will work fine for a minute or two. Does anyone have any advice? It's a brand new computer, only about a month old.
