I have been using the EP1 and now also the EP2 and have had difficulty with the rear control panel. It seems I am always inadvertently hitting the WB button (Most often) and others less often and changing setting without realizing it. A: Does any one else experience this B: Has anyone found a shooting method that helps lessen this issue. C: I do have big hands which of course is a problem but I have given the cameras to others to shoot with having thin fingers and small hands and they seem to experience the same problem. D: Maybe Olympus can put a lock switch on the back???
