In the HyperCard model, each card resides in a background. Since this is the
model upon which MC is based, I assume it uses the same object hierarchy
model (even though MC bkgnds are different animals from HC bkgnds).
That's why I would say you're experiencing correct behavior from MC.
Supporting evidence: if you have a stack where a given bkgnd is shared by
more than one card, open it and type in the message box:
answer the number of cards in bg 1
