Andu:
Thank you very much for your helpful info. I've said before I'm the complete computer dummy, but I'm certainly learning, and my son will show me what to do when he comes next time.
I seem to have opened a can of worms, and I apologise to everyone for taking up so much space here. As I told PPRuNe Pop the other day, on the advice of Kookabat, I spent a considerable time typing a precis of my service (over 6 years) on the "WW11 Brevets for RAF Pilots" site, but on trying to send it, it disappeared into space. There are so many things I remember of those years, my stories would make a whole chapter of a book, much too much to record on the web, altho' I've typed out many of them.
Thank you for your interest......TTFN......BS
