I have a new system running XP Pro, ATI TV Wonder 600, GEforce 7600gt. I am getting a pop up box when I shut down the computer. I think it refers to the Catalyst media software that controls the Wonder 600 card, but I don't know if I need to worry about it or how to correct it. The pop up box says "catalyst dll can't be initialized because the system is shutting down" or something similar to that. So far, it has not caused any problems shutting down.
