[PyQt] No reply - did I post wrong?

[Giacomo Lacava]

Pete,
you're not doing anything wrong, it's just that probably nobody  knows
an answer to your question (like me) or they are all busy, or or or...

If I were you I'd try to contact the ctypes people as well, maybe they
have an idea of why that call would fail.

Cheers
Giacomo
