"Windows Explorer has encountered a problem and needs to close, we are sorry for the inconvenience." and then a bunch of crap under that.....i get this error when i click anything on the desktop(shortcuts) or on the start menu. but only the first time i've clicked in a few minutes, for example: i click my computer and it comes up, then everything on desktop and the start menu will disappear, reappear and i can do whatever i want without any errors. running win xp home. anyone else had this before or know what's wrong please help, it is VERY annoying, and i really don't want to reformat.
