Drag operation should not start if e.ClickCount != 1...
Correction:

        static void DragSource_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            // Ignore the click if clickCount != 1 or the user has clicked on a scrollbar.
            if (e.ClickCount != 1 || HitTestScrollBar(sender, e))
            {
                m_DragInfo = null;
                return;
            }
.......
