Why Does "remove" Actually "delete"?

Scott,

Just tried this with 1 stack…

on Card 1
group id 1009 (Group name = GrpTest2 ) <= 2 fields 

on Card 2
place button
on mouseUp
   place group id 1009 of cd 1 onto this card
   -- place group "GrpTest2" of cd 1 onto this card ## Also woks OK
   -- place background "GrpTest2" onto this card ## Also woks OK
end mouseUp

remove button
on mouseUp
   remove group id 1009 from this card ## Works OK - removes from the card, doesn't delete from stack
   -- remove group "GrpTest2" from this card ## Also works OK
   -- remove background "GrpTest2" from this card ## Also works OK
end mouseUp

I can place and remove the group with no problem, tried with the backgroundBehavior property set to true and false with no difference.

This all fails if the target group is nested within another group.
