Thanks for looking at this and giving feedback.
Unfortunately, this doesn't seem to work for me when running with
Maybe it has to have to do with Tkinter running in the background thread,
and tkraise not knowing about the IDLE window in the other thread (which
is on top).
If there were a global ontop function, that would do it. I'm starting to
think that it isn't even possible in WindowsXP with IDLE with processes...
