[Pythonmac-SIG] Should Python.app be an LSUIElement = 1 app?

Chris, I'm a bit confused, too.

Basically, if you're running /usr/bin/python or Python.app directly, you
still won't get a dock icon even if you're using appscript.  The app is
marked as an agent application -- still trying to figure out just what
that means.

Yep, that's what seems to be happening.

Excellent point.  I think what happens is that the system thinks Python
should be responding to it, and when it doesn't (because it's been
improperly promoted), it feels it might have timed out, and to avoid
losing your data, cancels the logout.  I assume there's some magic key
combo you could press while logging out to override that protection; I
just don't know what it is.
