That's a problem across the board with Tkinter and
Windows. If you check sourceforge, you'll find it on
the bug list. So far, nobody is quite certain whether the
problem is in Windows, Tcl/Tk or Tkinter, and nobody
is working on it, as far as I know.

It only seems to occur if you are using the command
line under Win 9x - it's reported not to be a problem
if you invoke the program from an icon without a
command window.

As far as I can tell, the permanent solution is to use
another graphics package. I'm very patiently waiting
for anygui to become useful...
