Stack menus

Thanks Ken, that clarified the color stuff.

I guess the fact that the armFIll and autoArm properties are not shown in
the IDE Inspector for a button makes it hard to figure this out!

Still puzzled by the message path though.  Using your example, I had a
mouseUp handler in a button in Stack2 which called a handler in Card 1 of
stack 2 so sounds like it should have executed.  Plus when I removed the
mouseUp handler from the button and re-titled the card handler to mouseUp,
all worked fine.  I'll see if I can check into that again.
