Dear try67
I just forwarded him to a page (by Adobe Expert) where I had hoped this will help him.
It could also be your side.
I don't think that it took a comment from another. Unless it is a personal good advice. I just wanted to help and free of charge
Sometimes we overlook a detail by quick reading. Is this never happened to you ?
