If you try to add a splitter window to a popout frame, the splitter window and contents will overlay the menu and toolbar of the popout frame.   As an example, in the toolkit Advanced sample, I removed the logic to add the pane, and instead added a normal tree/list view as follows:

BOOL CPopoutFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/,CCreateContext* pContext)
 {
 // create splitter window
 if(!m_wndSplitter.CreateStatic(this,1,2))
      return(FALSE);
 if(!m_wndSplitter.CreateView(0,0,RUNTIME_CLASS(CGUI_Ex plorerTree),CSize(300,100),pContext))
      {
      m_wndSplitter.DestroyWindow();
      return(FALSE);
      }
 if(!m_wndSplitter.CreateView(0,1,RUNTIME_CLASS(CGUI_Ex plorerView),CSize(100,100),pContext))
      {
      m_wndSplitter.DestroyWindow();
      return(FALSE);
      }
 m_wndSplitter.ShowTopBorder(false,3);
 m_wndSplitter.SetSplitterStyle(XT_SPLIT_DOTTRACKER);

 m_pTreeView   = (CGUI_ExplorerTree*)m_wndSplitter.GetPane(0,0);
 m_pFolderView = (CGUI_ExplorerView*)m_wndSplitter.GetPane(0,1);
 m_pTreeCtrl   = &m_pTreeView->GetTreeCtrl();
 m_pListCtrl   = &m_pFolderView->GetListCtrl();
 m_pListCtrl->AssociateTree(m_pTreeCtrl);
 m_pTreeCtrl->AssociateList(m_pListCtrl);
 return(TRUE);
 }

The explorer tree and list view displays correctly, however the menu and toolbar cannot be seen.  What am I doing wrong, or is this a bug in the LoadFrame logic?

Never mind.  I found the problem.  The sample was creating a default view in the OnCreate section.  I removed that and now the splitters work correctly.
