Thinking that it may be my internet security program that was preventing MA from working I installed a different internet security program and reinstalled MA. It did not help at all.
So then I got to thinking, what was a common thread to the whole situation.? The mouse was a common element so I just disconnected it to see what would happen. What happened was that MA acted like a screen saver again and came on by itself. As it turns out I was using a wireless microsoft mouse and apparently it automatically periodically sends out a signal that makes MA think the mouse has been moved. I switch over to a Logitech wireless mouse and MA has worked since then. Problem solved by switching the mouse.
Bet that one is a new one for the books.
Thanks for all the suggestions.
