Capt J - thanks for your reply. I imagine that I have the latest updates, except for returning to NS 7.1 which didn't appear to be available, because I downloaded this morning from Browser Central. In case I am not understanding you fully, I will go and consult!
It won't be for a little while though because Mrs. Cameronian has been calling me to Sunday lunch for some time! Please forgive me for valuing my neck!
