My apologies for the lack of response, but some domestic crises intervened and I have been away from my PC for some time. My sincere thanks to all of you. I've done basically what everybody suggested and FPSCX10 is working fine now - and so is FPSCX9! GREAT!
(I'm using DirectX 10 - downloaded the SDK (took 5 hours), but, for the life of me, I can't figure out where the DirectX 10.1 file is, nor where to install it. Never mind - seems to work fine on directx 10. (Of course, this shouldn't really be necessary - which is where this all started). Anyhow, my thanks to all of you once again - and in particular for the friendly manner in which all your help was given.
A quick personal note to Mr Valentine, if the Mod will permit: Pity you can't try the tradional South African "mampoer" peach brandy - liquid dynamite - no flames within 100 meters...
