That isn't the problem. I reversed the sensor on one RCX, and they both showed
it as being constantly pressed, so that must be the wrong polarity.
But I also tried moving it from input 2 to 3. Works fine. Same programs,
everything, it works in 3 but not in 2. But at all other times input 2 seems to
work fine. This seems strange to me. Anyone else seen anything like this?
