} Without adding the repaint() first, try forcing a repaint of the VisualGraph 
} ( e.g.: by moving a Vertex ). It should display the new text for the Edge.

} Calling repaint() is actually what happens when you right-click on a Vertex 
} or Edge ( in Normal State ), then modify the properties then click OK or 
} Apply.

I tried this, and I tried including a repaint() call immediately after
I set the text on the edge.  Neither works.  :(  Maybe I have some nasty
bug somewhere that I am missing.  Is there some way that vertices and
edges could get removed and re-added behind the scenes?
