Summary0001679: Strange paths when ports used

I'm trying to use GraphViz in connectin with UMLGraph.

Looking at a simple example produces strange behavior. The dot input
is in It's supposed to produce the graph
shown in class-eg.gif \<A HREF="b1730a.gif"\>here\</A\>. But instead, it
produces the graph shown in class-eg1.gif.

It looks as though GraphViz is forcing the edige to contact the rectangular node at vertical sides rather than horizontal sides. This doesn't happen when the count of edge going to a node is one but seems to happen when the count is greater than one.

If you have any suggestions I'd appreciate it.
Additional Information

When ports abut the exterior of a node, by default, dot tries to resolve the port to some exterior side so that the
edge doesn't go through any interior part of the node. The instance you provide is a case where all sides of the
port are exterior, which wasn't handled well.

This problem is now fixed, though the port resolution code still stand further refining.
