Tkinter icon

[Matthias Huening]

Hi,

when I try to change the icon of an Python/Tkinter application on 
Windows with:

from Tkinter import *
root = Tk()
root.iconbitmap('filename.ico')

I get a strange effect: almost everything works like expected, the window 
gets the new icon. But before it shows up, first a little window pops up 
and disappears again (it too has the new icon). Any explanations?
