To reply to my own question...
The VSS on my hand wired board was
not up to par. I added a direct wire from the
ICSP connector directly to the 2 VSS pins
of the PIC, and all is now well.

Sometimes a good nights sleep can be
my most valuable tool.

While I'm answering my own posts. 8^)
I had asked a few days ago about
MPSIM not reading the CONFIG files.
The program in this project checks if the
HSPLL Osc option is set so it can adjust
the timer prescales accordingly.
The code works fine in the chip. There is
a note somewhere deep in the help files
that states that MPSIM does not address
above FFFF. The config files are well above
this, so SIM always returns zeros.

Off to write more code,
Lyle
