I have the current software as of a week or so ago and I bought the blue LCD in the MPGuino main thread. Pushing the middle button doesn't do any good.
But I just found something disturbing with my multimeter. The middle button seems good, but the other two buttons are leaking electrons. I don't see a problem with the soldering, so I have to guess that these buttons are broken. Maybe the middle button isn't working because the unit thinks I'm scrolling up and down superfast?
I tested all the buttons before I put it together, so something must have damaged them somehow afterward. I can't think what.
