I have worked through the "Add a Docking Pane to your application" tutorial and everything is working perfectly, except for the restore of Pane positions...

In my MainFrame class I have lines of code like this (for each pane) of these in my header file:

    CXTPDockingPane *pwndProjList;
    ProjectListTabCtrl  m_wndProjectListWindow;

And in my OnCreate() method (above the code to restore the layout) I have a number of lines of code like this (for each pane):

    pwndProjList = m_paneManager.CreatePane(IDR_PANE_PROJLIST, CRect(0, 0,200, 250), xtpPaneDockBottom);
    m_wndProjectListWindow.Create(TCS_TABS | TCS_FIXEDWIDTH | WS_CHILD | WS_VISIBLE, CRect(0,0,0,0), this, IDGT_PROJ_LIST_WND);
    pwndProjList->Attach(&m_wndProjectListWindow);

This creates a pane containing a list control.

I have added the following code to my OnCreate() method after the above code:

    // Load the previous state for docking panes.
    CXTPDockingPaneLayout layoutNormal(&m_paneManager);
    if (layoutNormal.Load(_T("NormalLayout")))
    {
        m_paneManager.SetLayout(&layoutNormal);
    }

And in my OnClose method I have added the following code:

    // Save the current state for docking panes.
    CXTPDockingPaneLayout layoutNormal(&m_paneManager);
    m_paneManager.GetLayout(&layoutNormal);
    layoutNormal.Save(_T("NormalLayout"));
