hi,
I know i'm getting different results at each execution, because of the
rand() function, as it deals with some statistics... But the RANGE of
the results is VERY different with/without the namtrace!, as you can
see, with namtrace, the results are around 10%. without namtrace, the
reults are around 50% or even more... 

I cannot find any reason for this. Can you?

Thanx a lot...
