Hi, just 2 lines to tell not to think too much about that problem... it was solved, don't know yet how, but it was a very little thing... I've done again and again 1000 and 1000 tests, and at some time, it worked... Now I want to go back, and understand why it didn't worked before, so that we may write down 2 lines for other people that will fall in a similar problem. thank you, fi
