Yep, we clicked the light bulb and the output from the DIO-Get call never changed from "T" regardless of whether or not the switch was pressed. At the same time we put a multi-meter on the signal line connected to the switch and watched it change from 4.0v (switch open) to 0v (switch closed). I'm positive the switch and signal line are doing what they are supposed to, but the program isn't seeing the change on the signal line.
