WMC kicks on when quiting certain application

i know this is a very old post but since i was doing a search for guildwars players on the forums i figure i'll answer it incase someone else has this problem. the user or someone else on the user's pc set an argument in target location of the shortcut being used, in this case it would be something like gw.exe-mce telling the game it can be launched from WMC and also reopening WMC when the game is closed regardless of where it was opened from. to fix the problem remove "-mce" from the target field under properties.
