+Summary: TreeView: Endless loop calling CancelEdit and BeginEdit
+
+To refuse changes made to the label of a TreeNode and keep the label 
+editable, you can use the following eventhandler:
+
+void TreeView_AfterLabelEdit (object sender, NodeLabelEditEventArgs e)
+{
+	if (e.Label == null)
+		return;
+
+	if (e.Label == "REFUSE") {
+		e.CancelEdit = true;
+		e.Node.BeginEdit ();
+	}
+}
+
+However, on Mono this results in an endless loop and eventually a crash.
+
+To reproduce:
+1. compile and run the attached source code.
+2. follow the on-screen instructions.
