Modal dialogs run their own nested event loops.  This code shows it:

=====================
import wx
class FooDlg(wx.Dialog):
   def __init__(self):
       wx.Dialog.__init__(self, None, -1, "Just Testing")
       vbs=wx.BoxSizer(wx.VERTICAL)
       vbs.Add(self.CreateButtonSizer(wx.OK|wx.CANCEL|wx.HELP), 1, wx.ALIGN_CENTER|wx.ALL, 5)
       self.SetSizer(vbs)
       vbs.Fit(self)
app=wx.PySimpleApp()
foo=FooDlg()
foo.ShowModal()
=====================

I wonder if it is to do with the parent of the dialog not being visible?

I would love for that startup stuff to be simplified, and you are currently
looking at my best efforts :-)

The problem is that some of the tabs (wallpaper, ringtone etc) need to
know the pathname to where their data is stored when they get constructed.
Consequently that information has to be known before their construction.
That is why the code does the config stuff half way down the initialisation.
It also has to do fun stuff if the splash screen is still up.

I think a solution is for the various widgets to not load any data
when they get constructed.  They get told to load stuff later anyway.
However it is a bit of late change to make now :-)
