Yep, I think this is exactly the problem (though I could never
reproduce it), and, like you say, creating wxapp in
new_figure_manager() sounds like the right solution to me.  I
think this was part of the discussion with Marcin W. a month
ago, no??  Anyway, in backend_tkagg (the closest analogy I'm
familar with), Tk.Tk() is created in new_figure_manager.  It
seems that with other windowing systems, it's ok to create the
mainApp (ie, who will run the event loop) if needed in show()???
Perhaps it would make sense to have this be more uniform across
the different backends?

Thanks,
