I'm actually surprised to hear you, as a HyperCard user, say this,  
i.e. that is a surprising feature.  I may be wrong about this but I  
had thought the background property was implemented in large part for  
compatability with HyperCard.  And while it's been years since I've  
used HC, as I recall in HC, a click outside any other objects would  
go through to the background which covered the entire card.   
Personally, the feature that  I found surprising when I started using  
rev was that you could have more than one background.
