Yeah, since I was just testing it, I didn't bother to make it visible.

Ok, so I changed the binding to <Button-1>, and made the frame bigger, 
and it works, but I still can't get it to work with any of the keystroke 
bindings, only the mouse.  Or, at least not with <Return>, the <F1>-<Fx> 
family, or <Control-Shift-Up>.  Seems odd to me.
