If I look at the XML in graphml It shows more edges than I expect. So I guess they are loop back edges, but I can't see them in the drawing. What did I do to be blessed with these, and is there a way to find and eliminate them? Since, they are making the code that I wrote which chews on the resulting graphml cranky - and we wouldn't want that!
Thanks, yEd is a very sweet bit of software.
