I composed a careful reply to this message earlier today.
I've not seen it in the thread.
I came back to check and to try to post this message. I was offered the opportunity to "use recovered" to rescue what I wrote. This blank box opened.
I have not lost interest in this thread. I see I should have composed my reply in Word and pasted it to the forum so that I could copy and paste it a second time. It will take more time for me to recompose than I have just now. I have a travel schedule to meet. I cannot return to this thread until Saturday, 12 April. Please do not consider it abandoned or judge that I have lost interest.
Thank you
