It crossed my mind too, but ESD could not explain the fact that _TWO_ Pic's
developed an equal problem at the (for me) same moment.

Oh, before I forget to mention it, I've programmed 16C77 Pic's with the
same
PicStart+ and all things went O.K.  No problems.

So, I can cancel-out ESD damage to my Pic's and PicStart+ (unless its
intermittent ofcourse).

Once fried a C64 disk-drive controller because of it, just when I remedied
the
problem it had.  Was not funny.  But a great example of ESD and
unforgettable.
