Worse, if I modify the code to add logs when reading the inputs ports,
the logs doesn't appear whereas "cd B; enter;" shows :

B [R]> inZZZ.read(i)
= OldData

B [R]> Port_test executes updateHook !
inZZZ.read(i)
= NewData

B [R]> inZZZ.read(i)
= OldData

So it seems that it is the "port mecanism" that is no more working on
my computer. Does anyone of you have an idea ? Do you experience such
kind on problem with 2.5 ?
