Hi Bob, Many thanks for the report. Makes me feel a bit easier. RB3 is used as an input for the CCP so I can't see why it should be affected, particularly when it it is disabled. I will download the new version of MPLAB, maybe they have fixed the problem. Anyone know when the 32-bit version will be released?
