Lordy, Lordy! I cleaned the terminals as suggested. Everything worked well for about a dozen exposures, then it reverted to the "clean terminals" message again. I did reclean them once more and it worked for five exposures then the message returned....
Are you thinking that condensation might appear on the surfaces of the contacts where I could see it or perhaps dry it out with a hair dryer? Or, are you thinking moisture may have gotten inside the lens somehow?
