Jeff at MeLabs has just confirmed what I previously deduced and posted here.

The setting of the second Config Word needed a change to PBP's assembler, which I assume has been completed in the current release of PBP (2.45).

Use the two work-arounds I gave you, or upgrade your version of PBP to the latest.

As I said before, whatever you do, DO NOT USE any of the FCMEN or ICSO defines as they can impact on the Oscillator settings. This restriction does not apply if you use the MPASM assembler.
