What version of Python? What version of Windows?  Which executable are
you running python.exe or pythonw.exe? Are you using Tkinter?
What version of Tk/Tcl?

Can you provide more details on "it only occurs when there's been
an uncaught exception".  It sounds like a very good area to look for
the problem - the way Tcl errors are passed back to Python.

Let's get some more info from the original poster - the 'known
problem' is specific to python.exe with Tkinter under windows 9x.

Can you boil it down to  minimal example program of starting Tkinter,
doing something to throw an exception, and then not being able to
shutdown? It would be great to nail this bug down. (And of course:
What version of Python? What version of Windows?  Which executable are
you running python.exe or pythonw.exe? What version of Tk/Tcl?)
