In a Lane diagram I am using the following code to detect a double-click on a row header:

       private void diagramView_MouseDoubleClick(object sender, MouseEventArgs e)
       {
           PointF p = diagramView.ClientToDoc(e.Location);

           if (e.Button == MouseButtons.Left)
           {
               Grid grid = flowChart.LaneGrid;
               RectangleF rect = new RectangleF();

               Header header = grid.GetHeaderFromPoint(p, ref rect);

               if (header != null)
              {
                     ...........

This works fine UNLESS the lane diagram has been scrolled horizontally (the row headers are fixed and don't scroll) - in this case header is returned as null.  Is this a bug?

I am using Version 5.3.1
Thanks for your help

Many thanks - that works fine.
