Hi, Tim.

This is one of those ones where I can't easily check my suspicions
because I don't have the namespace on my box. I can probably give
a hint or two, though. And I'll almost certainly find along the
way that you're doing something no-one's asked the wmi module to
do before and which, therefore, I don't support too cleanly!

No. 1 - get the latest release:

http://timgolden.me.uk/python/downloads/wmi-1.3.2.zip

which may actually solve the first problem if it's
what I think it is, and will certainly help you with
the second. If I'm wrong -- and even if I'm right :) --
feel free to post back.

The first one *might* be a symptom of a long-standing bug
I've just squashed which over-cached the WMI methods so
that any method call after the first one was attempting
to call on the *first* object again.

The second one is the slight gotcha that -- prior to the
latest release but one -- you had to pass method params
as keyword-only. Not helped by the slightly obscure error
message which even has me scratching my head when I forget.
I've fixed that in the latest release so please run it through
and make sure for me.

Thanks
