Perhaps we should go back  to the previous version. I would suggest to move
the GMFrame import after showing the splash screen (the diff is for release
branch):

                             workspace = self.workspaceFile)


as a result on my computer, the splash screen is showed earlier. It
probably won't effect the problem Moritz has, but it's worth trying. I also
saw someone mentioning calling Refresh() and Update() on the splash screen
after showing it. Then, there is a more complicated solution
