           Summary: Line Vertex hidden in class diagrams

- Create a new class
- Draw a aggragation line that loops back on the same class
  (This happens when you have a "singleton" or other type
   of class that contains a pointer to itself.)
- Select one of the vertexes of the line and move it
  down under the class.
- You can no longer move that vertex out from under
  the class.

I only say to do the above in order to illistrate a problem that I have run into several times on class diagrams. Sometimes when I do a cut/paste from one class diagram to another, the singletons lines get moved around. Most of the time it is just messed up a little. Other times the lines end up under the class box, and there is no way to get ahold of the vertexes to move them out from under the box.
