SubclassWindow causes stack overflow in CMainFrame::OnCreate()

[spectre72]

I recently upgraded my MS Visual Studio 2008 to Service Pack 1 to take advantage of the MFC enhacements (Feature Pack).

I orginally had an MDI app in which I had changed the background in the main client area to tile a company logo. I originally followed the instructions in MSDN: Q129471. Worked beautifully since MS VS 2002 .NET.

CMainFrame was derived from CMDIFrameWnd, and my overloaded CMainFrame::OnCreate() looked like

     BOOL CMainFrame::CreateClient(LPCREATESTRUCT lpCreateStruct, CMenu* pWindowMenu)
     {
         if(CMDIFrameWnd::CreateClient(lpCreateStruct, pWindowMenu))
         {
                m_MyMdiClientWnd.SubclassWindow(m_hWndMDIClient);
                return TRUE;
          }
         else
               return FALSE;
       }

BUT, now with the CMainFrame derived from CMDIFrameWndEx, the call to SubclassWindow() causes a stack overflow.

Someone else has had to come across this same issue!

CMainFrame::OnCreate and CMainFrame::CreateClient are different functions, isn't it?
