I get this error fairly often (which crashes my application in  IE ) :

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
   at System.ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument argument, ExceptionResource resource)

What can be done to fix this problem?

Could you copy here the link's property values shown in the debugger's watch window when the exception is thrown?

Here are all the link properties set:

           link.AutoRoute = true;
           link.BaseShape = ArrowHead.Circle;
           link.BaseShapeSize = 7;
           link.Dynamic = false;
           link.HeadPen = new Pen(Brushes.Green, 2.0, DashStyles.Solid);
           link.HeadShape = ArrowHead.DoubleArrow;
           link.HeadShapeSize = 7;
           link.IntermediateShape = ArrowHead.Circle;
           link.IntermediateShapeSize = 5;
           link.Style = LinkStyle.Bezier;
           link.Text = "";
           link.TextBrush = Brushes.Blue;
           link.ToolTip = "Link hint here ...";

Disable the IntermediateShape for now - it does not work that well with Bezier links. We'll fix this next week.

I found that setting link.AutoRoute = false;
prevents my crashes so far. Which is good for me.

And somehow I don't see the IntermediateShape anymore when I set this.

Is this a 'Feature' or a bug?

IntermediateShape is shown for Bezier links only if they have more than one segments, and thus the problem happens when the routing function adds new segments for some more complex paths.

When it's fixed, how do I get the fix?

I bought the product at ComponentSource.com
