Code fixed in ReadSection, I don't know why I wanted to have both quartet of one byte to be fail to raise it ans not just one of them...
My mistake was about the use of a logical and instead of a or.
Thx again

, btw I'll stick it to 90% as you see I like bugs :P
To all, do not hesitate to push this to the limit, I didn't share it to receive roses but to be sure it will profit to all, and also aas you may know it's always better to have someone else check your on work for validation, at least that's what we do when building test solution in my company.
