Does anybody know a reason why a process won't run on a popup form with the panel operation Close button 'Execute Process After Close' ?

It works when displayed in a panel, but not popup.
I've even added a debug BO and placed a 'Create Debug with ....' inside the process to see if it runs, or if it just fails... but it doesn't even run.
Do popups run in their own magical space or something? Or are they a thing of the past ? Because there seems to be a lot of things in AwareIM that I can't seem to get functioning properly with popups ... things that seem like they should Just work.
Thanks.
