Thanks once again. !!!
Thanks also for your compliment about not being dumb. In a way you are right since I have posted over 40 walkthroughs. They are I think pedantically accurate. However I never was one of the sharpest tools in the shed. And now age (coming up for 87) and very badly failing vision make things much more difficult
.
I apologize since I could have saved you the bother. I only read the poor description and did not carry on and look at the very much better graphic. If I had I would have solved it immediately – but I passed that spot a couple of dozen times or more without knowing from the graphic or ever having noticed a hotspot there !!!!
