It happened a few times that I was asked by customers, who had just finished downloading the YaSM Process Map, why "the links in Visio don't work".
It always turned out that the links (say, from a Visio shape to a linked diagram) actually worked as promised, but two points need to be kept in mind:
First, please ensure to extract (unzip) your delivery archive (which comes in ZIP format).
