i have opeed winamp and chose to associate it with none of the media files then close winamp open it again and associate it with them all again and it will change the icons, but after reboot the icons are back to the globe ith the video film thing. how do i keep the icons from changing? this isnt a major issue but is very annoying. if i unregister the dll that contains those three icons would that work? does that dll belong to anything else? thanx in advance
