Thanks again that clears it up right. For anyone interested here's what I had to do...because I'm a little slow with the details.
I had to make sure that the windowcloser.pd was not a subpatch of my main patch, of which the popup window was also a subpatch.
I still wanted to send from the same bang that applied changes in my popup window. It crashed PD, even though the windowcloser.pd patch, where the [r closeit]----[pd-popup.pd menuclose( command fires, is not a subpatch of the main patch.
So, I added a delay in the windowcloser.pd patch between it receiving the bang and actually hitting the message-command box (50 ms, excessive but who cares); this seems to allow me to close my popup window with one click in the very window that I am closing. Yea!
Of course windowcloser.pd must run in the background this entire time, but I imagine it will be able to provide similar functionality for any number of my subpatches...now how much I/O glitching is this opening and closing of windows going to cause me? I don't want to know.
