    maybe you reach the maximum current source of your PIC. How about if you trade your LEDs to 1-10K resistors???

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    The outputs are going to a ULN2003A and while I haven't measured it, the datasheet for the ULN2003A says it requires 1.2mA per pin.....this is well below the 200mA maximum by the PIC. The PIC is supplying roughly 19.2mA to activate the outputs.
