Thanks Raleigh,
I see the components you describe and the problem seems to be the mechanical switches - they are frozen. I can force some of them to move, so I now know what needs to be fixed first. But how should the pushbutton switches work? When you push a new button, is the currently pushed button supposed to "un-push"? Or, do you push the current button to un-push it and then push a new button?
