Joe,
Unfortunately, I think you're analysis is right. Probably a hardware
problem. That stock patch does not behave like that on my AN. The symptom
of immediately going to a value when moved is the way a digital sensing
circuit behaves with a bad control. Basically, the software doesn't waste
valuable time continuously polling the controllers - it relies on interrupt
hardware signals to change a value. So what's going on is your ribbon is
somehow stuck on it's lowest value, but the operating system doesn't know
about this until you generate an interrupt by changing the controller - and
in your case when it's detected by the software it always changes to the
lowest value.
If you're brave and not intimidated by a screwdriver, pull out the 30 or so
screws on the back of the AN1x and check any connectors to the ribbon cable.
They may be just dirty or loose and re-seating them might be all that's
wrong.
