Thanks Tim.

The suggestion to run Python -v was perfect: I must read about these command
line options!

It revealed an old copy of inspect.py on a hard drive I had not searched
because there was no way the Python interpreter could find it there <sigh>.
I still do not
understand how it was found because I supposedly do not define PYTHONPATH so
that everything used is in \PYTHON22\LIB\site-packages.

Thanks again.
