"Threads combined. The general idea is that you're not supposed to start two threads on more-or-less the same subject, especially when those threads are running at the same time. It confuses people and splits the discussion, and may be the reason why you didn't get comments on the second thread."

Ok didnt comment on this before, but yes that makes sense. I maybe get waylaid a little in my enthusiasm. :-P

I must also say that there have been a lot of very useful comments here, and it is all very much appreciated.
