This have to be a silicon batch problem. See the tons of errata on the Microchip website. But some use them and works a treat... it's certainely not even a PBP related problem.

Hum humn.. i saw almost the same question/comments on some competitor product.. and they mostely comes up with the same conclusion.

The Darrel suggestion could be a real great workaround... but i just hope it will never ends up in an endless loop... wich is... a real pain in the ...

I'll try those i have here to see if i'm better lucky.
