Silent is right that what I wrote earlier was a crap, indeed. I should not have written that crap. I need have a great vacation: it is middle of summer. Thank you for reminding me that today is Friday the 13th, something bad has to happen. It is cleared. I am leaving for a week end vacation. It is a right time for me to leave, and say to all in this thread: have a great week end, guys. Thanks again. GP
