COM error/exception in Python, but not in VB (no dispatch interface available)

Thanks much for your suggestion.  That gives me direction to focus.  I'll
see what information I might be able to extract from the developers of the
library regarding the return value.  The documentation doesn't explicitly
mention what's returned (and it's not open source).  I am not intimately
familiar with COM, and so wouldn't even know how to approach programatically
inspecting the return value.

Thanks very much for the suggestion.
