Ooops - sorry about that. That was never my intention; it's a long time
since I've joined a mailing list that has the default reply address for
messages distributed set to "poster" rather than "the list" so I hadn't
thought to check the "To:" field was set correctly!

Yes - there was always that possibility. Can't see why though in this
case as everything, Qt, Python24, MinGW etc is 32 bit just running on
the 64 bit system.

Thanks for that suggestion. FWIW though, I've now downloaded and
installed using the Python 2.4 version installer from the PyQt site and
it seems to work ok.
