I know it was a computer glitch. Road generally knows what he is talking about, so I was trying to find a way to fit the two together. If he was right, maybe it was voltage irregularities that caused the computer glitch. It would explain why only the computer controlled lights were affected. Now if road's info was incorrect, none of this matters and it was just a hardware or software fault in the computer system. In the computer controlled lighting system we had installed in my school's auditorium, it felt like the problems were 50/50 computer vs. power system. Thing was, the power system problems would initially look like computer problems. You'd think the computer wasn't sending a command to the lights, but it was actually a power surge that messed up the settings of a power relay down the line. PITFA
