Thanks for your advice 3Run- I did not ignore your advice, far from it - I just don't think I am skilled enough to win a competition against my fellow 'gamers'.(having seen some of their work).
I am 87, the memory isn't as good as it was, and I am finding frustration is getting the better of me !!
I have paid for the upgrade, and am disappointed with the meager difference to A7 It only means just a few less 'sticky buns' for my next birthday !! - if I make it.
Again, thanks for your help - David.
