Glad to read your assessment that my problem is probably less serious. I tend to agree. I've cleaned the contacts and am ready to give it a good workout in a couple days. Stuff is in my way for the time being. :) Jack

That was the mirror flopping around. So, Jack, you're probably looking at something less serious, perhaps just dirty contacts, as CRIS suggested.
