Hello Brian I think the source of your problem is that the second instance of Wall_clock doesn't get deleted in the interval doctest. This is critical, because the is_instanced attribute is reset by __del__.
> def interval(self, interval_name = None): > ''' > >>> # print "Testing interval (intentional fail)." > >>> wc = Wall_clock() > >>> del(wc) > >>> wclock = Wall_clock() As a quick hack, try adding the following line here: >>> wclock.__del__() HTH John Ridley Send instant messages to your online friends http://uk.messenger.yahoo.com _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
