Ok, I give up.  

What's the _probem_ with allowing these poor little windows to each have their
own IDCMP's?  

It doesn't seem as though it would require more code for each window to have
its own IDCMP -- in fact, it seems like a much simpler/safer way to go than
the alternative.

Am I missing something?
