LoadCommandBars problem if Ribbon and Menu present

I'm incorporating a ribbon into an existing app, so want to give users the option of having the "old" look (menus plus toolbars) or the "new" one (ribbon). For this reason, I want to load menus, toolbars AND a ribbon and let users turn off whatever they don't want to see. Although this largely works, there is a redraw problem when both ribbon and menu are present together, which appears after SaveCommandBars/LoadCommandBars restores the screen layout. This effect is present in versions 10.4.0 and 10.4.2.

 

To show this I've taken the RibbonMDISample, added a menu bar:

CXTPMenuBar* pMenuBar = pCommandBars->SetMenu(_T("Menu Bar"), IDR_MAINFRAME);

plus an OnClose handler to save the command bar state

void CMainFrame::OnClose()
{
    SaveCommandBars(_T("CommandBars"));
    CXTPMDIFrameWnd::OnClose();
}

The first time the program runs, the expected appearance is found:

 

 

However, after re-running the program, at which point LoadCommandBars attempts to restore the appearance, what we get is the following, where the menu bar is positioned at the very top of the window:

 

 

Any chance of correcting this? The sample project showing the bug is here: uploads/20070204_102933_Bug_in_LoadComm.zip

Excellent! That works a treat.
