DOS-Shell hangs up, python/Tkinter

[Markus von Ehr]

Hi,

when I start my python/Tkinter apps out of a MS-DOS shell
and kill the app, very often the DOS-prompt doesn't come back,
the Shell hangs-up.
Anyone can tell me where the problem is?

Thanks in advance,

Markus

This is a "known" bug in Tk.

The workaround:
use pythonw for now........

I've been patiently waiting for AnyGUI in the hopes that it would
provide the ability to use a working graphics library under each
environment. Unfortunately, I haven't seen any progress posted
on AnyGUI in a while. That may mean they just aren't keeping
their projected next release date updated (I hope).

The problem is that with pythonw I don't get the Debug "prints".

Of course, I had a similar problem. There have been many threads
discussing this issue. There are also some cookbook recipes about doing
this ...... I chose to have a method in which I can choose to have
stdout/stderr go to a (dynamic) Tkinter window which pops up when there is
'something' printed. That way, I "know" when something got printed because
the window appears.

I would be glad to mail it to you if you would like (although it's a little
over 130 lines, I hate to waste newgroup bandwidth). I would post it on my
website but ... it looks so dumb I hate to advertise it.
