TIG:
Thanks for the feedback. I looked at all, as best I can, but do not find anything wrong. Everything had been working fine then all of a sudden things changed. FORTUNATELY, I had a backup and upon restore all was fixed and no further problems currently exist.

I tried “zoom extends but it did not solve my problem by itself but in conjunction with what Gaieus said read the solution is there.
Dave and Gaieus:
“Update Scene” solved the problem. I will never forget!
Gaieus:
As always, thanks a lot! In regards to #1 I think I did something and I have no idea what it could have been and I cannot find the specific cause. I think you identified the probable cause. Restore from backup solved the problem.
