Thomas, Another thought. Does the ICD possibly have greater driving capability than your PIC? Or maybe it handles capacitive loads better than your PIC. Just thinking out loud.

(Connected to the one node out of 12 that always fails.) But not when the same code is programmed into the PIC. Including leaving the ICD connected but released so the code can run. This is too obvious for me to comprehend. Can one of you point out the OBVIOUS to me? Tom * | __O Thomas C.
