A black area appears in the tab control of a CTabView and the taskbar preview window of a VS2010SP1 MFC MDI tabbed application, if the feature EnableMDITabbedGroups(TRUE, ...) is added to the CMainFrame::OnCreate function.

I posted this problem already on the MSDN forum:
http://social.msdn.microsoft.com/Forums/en-US/vcmfcatl/thread/c59d8eb0-046a-464c-bf38-91499fd91110

and David Ching David Ching DC Software Design, Inc. (MVP) told me to report this problem to connect.

Details (expand)

Visual Studio 2010 SP1

1) Load the sample "TabbedView" of Visual C++ 2008 Feature Pack in VS2010SP1
2) Start the application and add a second document with "New".
Look at the taskbar preview window you will see no black area in preview window.
Move the mouse over the preview window -> you will see no black area in the tabcontrol.
3) Add the following code to the OnCreate function of the MainFrame.cpp file and restart the application:
CMDITabInfo mdiTabParams;        <br/>        mdiTabParams.m_style = CMFCTabCtrl::STYLE_3D_ONENOTE; // other styles available...
        mdiTabParams.m_bActiveTabCloseButton = TRUE;     // set to FALSE to place close button at right of tab area
        mdiTabParams.m_bTabIcons = FALSE;    // set to TRUE to enable document icons on MDI tabs
        mdiTabParams.m_bAutoColor = TRUE;    // set to FALSE to disable auto-coloring of MDI tabs
        mdiTabParams.m_bDocumentMenu = TRUE; // enable the document menu at the right edge of the tab area
        mdiTabParams.m_bTabCustomTooltips = TRUE; // enable tool tips for MDI tabs
        EnableMDITabbedGroups(TRUE, mdiTabParams);

Start the application again and add a second document with "New".
Look at the taskbar preview windows you will see a black area in one of the preview windows.
Move the mouse over the preview windows -> you will see a black area in one of the documents (the inactive tab) in the tabcontrol of the application.

Is there a workaround for VS2010 SP1 available? I have the problem in a real application.
Thanks,
Andreas.
