Ok, but what if you're the top stack in the stacksInUse and there's another
stack below you that also has a doMenu handler that closes its windows?  If you
send the command straight to HyperCard the other stacks never get it.  I've
been wrestling with this general problem (passing on a message so other stacks
get it but still doing something after the message is "finished") and I haven't
come up with a good solution.  I've resorted to setting a global flag and
checking it in an idle handler, but I don't really like doing it that way.
Would it be better to find my stack's place in the stacksInUse list and send
the message on to the following stack?  Any suggestions?
