Use pythonw instead. Then it doesn't hang. Nobody knows how to fix it, or
even what causes it (follow the link).

Fredrik Lundh has provoked the same problems with pure Tcl/Tk apps run from
a wish shell -- no Python components involved. That is, there's no reason
to believe Tkinter or Python have anything to do with this.

Win9x suffers many flaky behaviors related to consoles and processes.
pythonw appears to avoid the hangup problems simply by getting the console
window out of the equation. Without MS's source code at hand, I doubt we'll
ever get a deeper understanding than that.
