[Netron-graphlib] GraphControl freeze when moving nodes, layout = SpringEmbedder and AllowMoveShape = true

[Helge J. <hel...@sl...>]

Using NetronSourceCodev21.zip, creating a 3-node graph which uses 
StringEmbedder and AllowMoveShape = true the application freezes after 
some 1-5 "moves" of nodes. Code-excerpt at the bottom of the mail.

This is probably related to me missing synchronization or something, 
perhaps the layout should be disabled while moving? Anyone got a hint on 
how to resolve this situation.

     private Netron.GraphLib.UI.GraphControl visiblegraph;
[...lots cutted...]
     public Form1()
     {
       InitializeComponent();

       visiblegraph.AddLibrary("BasicShapes.dll");
       visiblegraph.AllowMoveShape = true;
       visiblegraph.GraphLayoutAlgorithm = 
Netron.GraphLib.GraphLayoutAlgorithms.SpringEmbedder;
       visiblegraph.EnableLayout = true;

       Shape[] shapes = new Shape[3];
       for (int i = 0; i < shapes.Length; ++i)
         shapes[i] = visiblegraph.AddNode(
                         i.ToString(),
                         new PointF(10.0F*i, 50.0F*i));
       for ( int i = 0; i < shapes.Length; ++i )
           visiblegraph.AddEdge(
                   shapes[i].Connectors[0],
                   shapes[(i+1)%shapes.Length].Connectors[0]);
     }
[...lots cutted...]
