BUG: CXTPSplitterWnd - can't move splitter!

   Hi;

I found a bug that can be reproduced with the SplitterWindow sample of the toolkit. To reproduce add another CXTPSplitterWnd to CMainFrame class and then modify the CMainFrame::OnCreateClient() function as shown below:

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/, CCreateContext* pContext)
{
    // Create the splitter window with two columns
    if (!m_wndSplitter.CreateStatic(this, 1, 2))
    {
        TRACE0("Failed to create splitter window\n");
        return FALSE;
    }

    Splitter2_.CreateStatic(&m_wndSplitter, 2, 1, WS_CHILD|WS_VISIBLE, m_wndSplitter.IdFromRowCol(0, 0));

    if (!m_wndSplitter.CreateView(0,1, RUNTIME_CLASS(CView1), CSize(0, 0), pContext))
    {
        TRACE0("Failed to create CView1\n");
        return FALSE;
    }

    if (!Splitter2_.CreateView(0,0, RUNTIME_CLASS(CView2), CSize(0, 0), pContext))
    {
        TRACE0("Failed to create CView2\n");
        return FALSE;
    }

    if (!Splitter2_.CreateView(1,0, RUNTIME_CLASS(CView3), CSize(0, 0), pContext))
    {
        TRACE0("Failed to create CView3\n");
        return FALSE;
    }

    //if (!m_wndSplitter.CreateView(1,1, RUNTIME_CLASS(CView4),
    //    CSize(0, 0), pContext))
    //{
    //    TRACE0("Failed to create CView4\n");
    //    return FALSE;
    //}

    CRect r;
    GetClientRect(&r);

    m_wndSplitter.SetRowInfo( 0, r.Height()/2, 0 );
    m_wndSplitter.SetColumnInfo( 0, r.Width()/2, 0 );

    return TRUE;
}
Now try to move the verticla splitter. I can't - it only judders!
Has anyone ever found a solution for this issue?
