AVR-Chat

It is very, very, VERY UNLIKELY you have stumbled across a CPU problem. It
is very, very LIKELY your code is the problem.  Unless you show us your code
and how you built it (what compiler, etc), there is little anyone can do to
help you.

Cheers!

Changed vector names from ZCINT0 to EXT_INT0 and PBINT1 to EXT_INT1 per the 
168 data manual. Still the same results. More head banging.
