The thought that comes first to me is this would be an excellent option to have if/when we start including these types of diagrams in pamphlet files - hyperlinked pdf for pdf, image map png for html. But I think that's a bit down the road at present. Cheers, Cliff __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
