Try to add the nodes instantiated from the class below on the diagram with (any) label text, all is ok, then do the same but use one of the following strings as label text: “weee”, “ewee”, “eewe”, “eeew” 
we have nodes with those “special” names drawn different (label layout) that those with any other strings.
public class IconicNode : GoIconicNode
{
public IconicNode()
{
this.Initialize(null, 0, “Node”);
this.Initializing = true;
this.Image.Size = new SizeF(40,40);
this.Initializing = false;
}
///
/// get/set node label text
///
public override String Text
{
get
{
return this.Label.Text;
}
set
{
this.Label.Text = value;
}
}
}
IconicNode theIconicNode = new IconicNode();
theIconicNode.Text = “any”;
theIconicNode.Location = new PointF(40,40);
goView1.Document.Add(theIconicNode);
theIconicNode = new IconicNode();
theIconicNode.Text = “weee”; // ewee, eewe, eeew
theIconicNode.Location = new PointF(120,40);
goView1.Document.Add(theIconicNode);
