Lyle, I'd be honored. Feel free to change the name from 
#execute_nonmodal, if you can think of anything better.

For paralellism with modal dialogs, maybe #execute could also take a 
block, with roughly the same semantics as #execute_nonmodal: the block 
is passed an _accepted_ value (true or false) when the dialog closes. 
This could be added to my code in the form of an #execute_modal method:

     def execute_modal(placement = PLACEMENT_CURSOR, &block)
       @__FTNonModal_block = block

This would make it really easy to convert code from modal to nonmodal 
(of course there may be other implications you have to worry about, but 
that's not FXDialogBox's concern). If you use the block form, you avoid 
having to check for the numeric result (0 or 1), which I sometimes 
forget to do.

BTW, I didn't see your message on fxruby-users, and I'm guessing the 
reason is that the address was in the cc field. I think I've seen this
