whenever i add something (shortcuts or files) to the desktop, the icon will be duplicated. i tried deleting one of them, but the remaining one becomes disfunctional. i have to delete both, and restore one from the recycle bin. (incidentally, i can only see one deleted icon in the recycle bin). this works, until i add something else to the destop, or when the desktop is refreshed. the "phantom" icon(s) will then reappear. mine is a new machine with XP pre-installed. please help me eliminate this annoying "double vision". thanks in advance!
