This just happens once in a rare while, BUT, I think I'll ask, just in
case:  You probably double-checked that this 0.1uF cap isn't shorted,
right?  <G>  Yeah, you probably already checked, I know (Not trying to
put you down, just making sure here!)

A .1 uF cap shouldn't cause that problem, since in-socket caps of that
size tend to exist.  I haven't done lots of ICSP, usually /JW parts
(16C622's) until recently;  I have had a rare few caps come up bad.
(And worse, had some 10Base2 BNC "T"s come in new, and shorted;  That's
EVIL to not test those, I now test my own, to be sure they're good.
Locked up the whole LAN here!  Grumble!)

I don't think I've seen any such Vpp timing adjustment, haven't looked
for it <G>  My bet's on the cap being shorted, at a guess.

(Preparing to be shown how wrong I am here <G>)
