Hello Alex H.,

We have already fixed this warning. New versions of methods are below:
Source\Common\FrameShadow\XTPFrameShadowManager.cpp  
void CXTPFrameShadowManager::DisableShadow(HWND hWnd)
{
    CXTPSimpleCriticalSection::CLock lock(*m_pGuard);

    CXTPFrameShadow* pShadow = GetShadow(hWnd);
    if (NULL != pShadow)
    {
        Notify(&IXTPFrameShadowManagerEvents::OnFrameShadowDisabled, hWnd, pShadow);
        SetShadowThreadMessageHook(pShadow, FALSE);
        m_mapWnd.RemoveKey(hWnd);

        if (::IsWindow(*pShadow))
        {
            pShadow->DestroyWindow();
        }

        DWORD refs = pShadow->InternalRelease();
......
}

Source\TaskPanel\Themes\XTPTaskPanelVisualStudio2010Theme.cpp 
void CXTPTaskPanelVisualStudio2010Theme::RefreshMetrics()
{
.......    
            m_themeTreeExplorer->OpenThemeData(wnd, L"TREEVIEW");

            wnd.DestroyWindow();
        }
    }
}

Regards,
 Oleksandr Lebed
