You can try running "makepy.py -i", and select your type library.  This
will spit out some code, something like:

gencache.EnsureModule(...)

change this to:

mod = gencache.EnsureModule(...)

And you should be able to create any of the class objects in the makepy
module - eg:

ob = mod.TheClassName()

If you search deja news, there should be lots of info about this - but
generally relating to "Lotus Notes", which also has the same problem.

[BTW - drop them a line, and tell them they should fix their objects :-]

Can you believe that we have never been able to recieve arrays of
IDispatch or IUnknown objects?!?!?

If you tried, you would have got "SystemError: NULL result without error
in call_object"

:-)  This was fixed in 129.  But 129 hasnt made it public yet - I will do
this as soon as I can log back in to starship!
