I am trying to convert a cross-platform Python/Tkinter application to
use Twisted and have run into a problem: at least on MacOS X I can no
longer quit the application.
I have appended a minimal script showing the problem.
This is probably not an issue on unix and WIndows because I find I have
to add my own Quit menu item anyway, so I can make it do what I like.
But on MacOS X with Aqua Tcl/Tk that item is added by the system and its
meaning appears to be hard-wired -- I suspect to it calls "quit" on Tk's
mainloop, but I don't know.
Any suggestion for a workaround would be most appreciated. Also if this
is not a known issue I will file a bug report.
"""Script showing failure-to-quit bug
At least on MacOS XO 10.5.6 with twisted 8.2.0, python 2.5.2 (from
python.org) and Aqua Tck/Tk 8.4.19 the File>Quit menu has no effect and
typing ctrl-Q causes the menu to briefly highlight (as usual) but has no
