Node Reposition makes nodes disappear

Weird problem - hoping somebody can help me with it. Trying to do a simple drag and drop inside a UltraTree. Here is my sample tree - taken from a sample

groupTree.Nodes.Add("Continent:North America", "North America");
groupTree.Nodes.Add("Continent:South America", "South America");
groupTree.Nodes.Add("Continent:Antarctica", "Antarctica");
groupTree.Nodes.Add("Continent:Europe", "Europe");
groupTree.Nodes.Add("Continent:Asia", "Asia");

When I drag North America into South America both nodes disappear!!! But when I drag South America into North America code works just fine - in other words it seems to work when dragging down but not up.

Below is my Drop routine.

        private void groupTree_DragDrop(object sender, DragEventArgs e)
            Point pt = ((UltraTree)sender).PointToClient(new Point(e.X, e.Y));
            UltraTreeNode DestinationNode = ((UltraTree)sender).GetNodeFromPoint(pt);

            if (e.Data.GetDataPresent("Infragistics.Win.UltraWinTree.SelectedNodesCollection", false))
                SelectedNodesCollection selectedNodes = (SelectedNodesCollection)e.Data.GetData(typeof(SelectedNodesCollection));
                selectedNodes = selectedNodes.Clone() as SelectedNodesCollection;
                //Sort the selected nodes into their visible position.
                //This is done so that they stay in the same order when
                //they are repositioned.
                for (int i = 0; i <= (selectedNodes.Count - 1); i++)
                    UltraTreeNode aNode = selectedNodes[i];
