Yep.

No, not explicitly.  Default on the EECON1 register is to have WREN off,=20
but I can still force that in my init routine.

Hmmm... interesting idea, which I can try easily.  I'm going to setup a=20
relay on a 0.1-Hz output from a function generator to see if I can=20
reproduce the issue with repeated power on/offs, and then I'll see if=20
these changes make any difference.
