No.  Hypercard is a foreground only application-- when switched to the
background, Hypercard (should) sends a suspend message to the current card.
After this message, the next message (should be) sent is a resume message.  (We
have had very little luck with the reliability of either message).

It might be possible to run a backgrounding XCMD, although I would suspect that
it could not use any SendCardMessage, EvalExpr, or other action that causes
some sort of script action to happen.
