The Mac doesn't like stuff like this. Yeah, it used to "work" but for 
each version things in event loop handling keep changing.

Your best bet is to do your "work" in a thread while .exec()ing the 
dialog. Then the main window UI's event loop can spin normally.

I'm currently dealing with a whole mess of problems when I pop up 
dialogs they appear behind Finder windows for some reason.
It's a mess.
