Music not stoping when exiting level

[Rector]

Do you have the fuction "StopMusic(float afFadeTime, int alPrio);" in your "void OnLeave()" function? That'll cause the music to stop whenever you leave the map, which should work just as well when you exit to main menu. It might fix it, but there's no telling since it's not included in the main game's script files (at least most of them, haven't gone through all).
