[Pythonmac-SIG] Re: No os._exit() in MacOS? (fwd)

[David Eppstein]

This is regarding some problems I've been having with quitting W apps in 
MacPython -- Just found a workaround and suggested forwarding to this 
list. I've put the problematic source online at
http://www.ics.uci.edu/~eppstein/noquit.py

Ok, I managed to work around the problem: it seems to be a bug related to
the SIOUX output window. Please post a followup to the macpython list, as
I have no idea what exactly causes it -- it *is* a bug, and Jack should
know about it.

Here's the workaround recipe:
Drop the resource file belonging to your app (<appname>.rsrc) onto
EditPythonPrefs. Choose "Default Startup Options". Choose "Delay console
window until needed" as well as "Keep stdio window open on: *never*".
(Those are good settings for W apps anyway.) Now build your applet again.

Good luck!

Just
