Are you running your code from within idle? It wraps your script in something like try: # run script except: # show traceback (Have a look at InteractiveInterpreter.runcode() in code.py if you are interested in the actual code) So your except hook never gets to see the exception and therefore won't be invoked. Run your script from the commandline and you will see the behaviour you expected. Peter -- http://mail.python.org/mailman/listinfo/python-list
