When I do a ctrl-alt-del I notice that there are two instances of rundll32 running. Why is that? I just installed my new video card and a new CDRW drive, would it have anything to do with that? I'm thinking I only need one running at most--if that's an incorrect assumption please fill me in here. But I don't ever remember seeing two running until recently. Can anyone offer an explaination?

(sorry for all the questions lately..)
