PointValueEvent (of ZedGraph.ZedGraphControl) is raised multiple times.
When I move my mouse cursor over a value point in the graph the PointValueEvent is raised multiple times.
The exact # seems to be random (3-10).
More importantly if I actually return a tooltip string in the event handler the event is raised repeatedly.
Only by returning an empty string could I prevent the event from being raised indefinitely.
When used as intended (returning a tooltip string) the result is that the tool tip flickers (as the value is updated with each event).
