Okay found it... ISR was acting on PortB not D !! Changed that, now
works perfectly.
Yes, I feel stupid, but how come that after one hour looking at the code
(okay it's late and I am very tired !) it's only juuuust AFTER you have
hit the "send email" button to the list, that you get the "bright"
idea ? Sorry for the noise.... hopefully the next question will be less
stupid...
