Uri I guess I am wrong. I mean no disrespect to you Uri, in fact quite the
opposit. I usually select threads to read by the author, such as Dr Hyatt, Your
self and few others. So I hold you in High esteem and have followed Movie right
allong. I mostly felt compelled to defend Fabien. His star has risen so fast and
it is really nice to see. I have two sons who make their Living from programs
on internet so I am very partial to you folks.
