My mouse cursor changes to random symbols. It will switch between the hand (like it's on a clickable link, but it's not), the horizontal double arrow (like it's on the edge of a window, but it's not), but usually it's two multicolored 'T's (one right side up, one upside down, about one inch from each other). It changes to other icons too. There doesn't seem to be any rhyme or reason to what or when it changes once it starts.
