I did notice one thing though, I had locked the panel and I notice that it had become unlocked (even though nothing had changed). I will watch it and see if it happens again and then dig out my apple mouse and keyboard, thanks for the idea. The main issue is it is very sporadic and it will be a test (for me) to see if I can remember to do the things that you suggest. Thanks, Ed
