Graph Axes.RemoveAt ArgumentOutOfRangeException

Hi!

I have a Graph with one horizontal and two vertical axes. I want to remove the second vertical. I do:

MyGraph.Axes.RemoveAt(2);

 And get:

System.ArgumentOutOfRangeException was unhandled

I checked and, the MyGraph.Axes array has indeed 3 elemets.

The Stactrace looks like this:

System.ArgumentOutOfRangeException was unhandled
  HResult=-2146233086
  Message=Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

  ParamName=index

Does anybody have any ideawhat could cause this?
