Hmm, that didn't work either.  Below is the full program I used.  Do
you think the fact that it's being run from a tkinter callback is why
it isn't working?  Like maybe tkinter is stealing/inhibiting these
Windows API calls while it's running the callbacks?

Running WinXP SP2, python 2.4.1, win32all build 204 here.

#!/usr/bin/env python

from Tkinter import *
import win32ui, win32con, win32gui

root = None
reps = 0

def show():
    hwnd = root.winfo_id()
    win32gui.SetWindowPos(hwnd, win32con.HWND_TOPMOST, 0,0,0,0,
                          win32con.SWP_NOMOVE | win32con.SWP_NOSIZE)

def reshow():
    global reps
    reps += 1
    print 'reshow(%d)' % (reps)
    show()
    if reps < 100:
        root.after(100, reshow)
    else:
        root.destroy()

root = Tk()
root.config(width=400, height=400)
show()
root.after(100, reshow)
root.mainloop()
