Just a thought, but how about opening your main window first as normal but
  hiding it (by positioning it offscreen), then having your integrity checks run
  from an Activate or Open event (for your main window), if those run OK then you
  can reposition your main window back on screen, otherwise display your error
  window... That way you have the correct parent and it will wait for a response as
  you want..
