This is an odd question but when I could not seem to add a single DockPanel.

m_rootDockZone = m_DockManager.RootContainer.RootZone
Dim first_panel_host As NDockingPanelHost = New NDockingPanelHost
m_rootDockZone.AddChild(first_panel_host)
first_panel_host.AddChild(panel)

following the code I will get two segments of docking pane.

Can i add a single panel without separator?
