It sounds strange because the 508 has been around for such
a long time the bugs must be well and truly out of it by now. It
may still be a window issue, or even a wonky chip

Of all the micros I've used that have JW parts for development
I don't recall any problems when moving to the OTP. That said,
what you're experiencing makes a good case for flash

uChip have obviously taken a shot at what will likely be most
used in production (C) and what will appeal to the hobbyist (F),
very generally speaking
