You might want to try manually setting the config. bits in the code. When you say "configuration bits dialog box" are you referring to the "development mode" menu? I believe this is for simulation and debugging, and does not actually set the bits.

For some reason the PS+ is sending the same config word ( all 1's )to the device no matter what selection I set in MPLAB. It is like MPLAB is failing to pick up the settings from the configuration bits dialog box. I see this with two different PS+ programmers so I don't suspect the programmer, although having said that they both are V3.00 firmware so maybe.....
