Neil, having the jumper in the AUTO position would not damage anything.

It's very strange that only certain programs would be affected. The only
thing I can think of is that some portion of the micro controller code may
have been zapped. You could try moving the Atmega chip to your other
controller and see if the problem moves with it.
