It beeps here when I go to any card where the group is placed, even  
between card that both have the group. (this is Rev 2.6.1 on OS X)

Do you have the backgroundBehavior property set?

However, if I set backgroundBehavior to false, it doesn't beep at  
all, which is what I would expect. Your "beep one time only" sounds  
like what should happen from a preOpenBackground handler.

Do you have any other preOpenCard handlers anywhere that might block  
this? (in card scripts, or other backgrounds)
