Dealing with empty groups...

Indeed, that is what I said - the empty group is not passing the message
- nor will it respond to the message itself. Having an object in there
solves the problem, and causes it to pass the message. 

Having a bottom layer object that automatically returns to the bottom
seems like it would also work - good idea.

Even though I have a couple workable solutions to the problem at hand, I
am interested in understanding the underlying issue, because I can see
other uses for empty and/or nested groups in the future. Are empty
groups supposed to behave differently than non-empty groups? I have also
noticed that with select grouped objects turned on - an empty group can
be selected as if it were an object. (not by clicking, but by using the
pointer tool to select a box that includes the groups edges)

Is this the result of an internal setting of some sort, or just an
accident of RunRev?

Sorry, but I thought you said that the empty group *wasn't* passing the
mouseUp message to the card:

If it *does* pass it to the card, then you've got your solution above.
If
not, the transparent object can be sent to the bottom after you've sent
other objects to the bottom (make it part of your "send to bottom layer"
code), so it remains "bottom-most". However, whatever works for you...
