I think its the donecanvasdialog message.  If you dont send that message
to resize the gop, then the patch closes properly.  So the act of
resizing the gop sets the dirty bit ... which makes sense of course
except when you're creating guis dynamically within objects.  Was this
updated in 0.40.3 because I only noticed this occurring recently.

I checked s-arranger, if you open it up and remove the control line to
the 2 resize messages in [pd setup] it works properly.
