Exception on startup after upgrading to 13.1

We upgraded from 10.1.1 to 13.1 and now get an exception on startup when we call ProcessShellCommand().

The actual exception is "The activation context being deactivated is not the most recently activated one."

We're using VS 2005.  The same code behaves normally with 10.1.1.  I'm wondering if I missed some step in the upgrade process?  Some property that needs to change?

The exception essentially occurs whenever LoadFrame is called.  In this case it's called by CXTPFrameWndBase::LoadFrame.

Here is a snippet of our InitInstance()

    CCommandLineInfo cmdInfo;
    ParseCommandLine(cmdInfo);

...

    CSingleDocTemplate* pDocTemplate;
    pDocTemplate = new CSingleDocTemplate(
        IDR_MAINFRAME,
        RUNTIME_CLASS(CBlaDoc),
        RUNTIME_CLASS(CMainFrame),
        RUNTIME_CLASS(CBlaView));
    AddDocTemplate(pDocTemplate);

    EnableShellOpen();
    RegisterShellFileTypes(TRUE);

...

    if (!ProcessShellCommand(cmdInfo))   // <<< UNHANDLED EXCEPTION!!
    {
        ClearSplash();
        return FALSE;
    }

    m_pMainWnd->ShowWindow(SW_SHOW);
    m_pMainWnd->UpdateWindow();

...

Sounds like a SxS problem I had. Make sure all modules you link together (Codejock and your own) are compiled with the same exact version of C++, MFC, CRT, etc. You if have external intermediate manifest files, you can look in there to see the library versions that were used for the compile.
