Not sure -- I'm going to run a verify pass on the flash before reprogramming 
next time this happens.

Well, I'm currently using the EasyProg programmer which programs and then 
tests/verifys at both 4.5 and 5.5 volts.  I used to use a PicStart+ until 1) 
its speed drove me mildly crazy and 2) it croaked.  I had the same problem 
with the same relative frequency with it.  That doesn't rule out a programmer 
related issue, but I'm hoping to consider that a little later is nothing else 
shows.
