I have a dialog with a scroll-bar of type CExtZoomScrollBar.

I initialize it in OnInitDialog like this:

BOOL CDataDlg::OnInitDialog()
{
    CExtResizableDialog::OnInitDialog();

    ShowSizeGrip(FALSE);

    m_wndZoomer.m_eSO = CExtScrollBar::__ESO_BOTTOM;
    SCROLLINFO si;
    si.fMask = SIF_ALL;
    si.nMin = 0;
    si.nMax = 100;
    si.nPage = 1;
    si.nPos = 50;
    si.nTrackPos = 50;
    VERIFY( m_wndZoomer.SetScrollInfo( &si ) );
    m_wndZoomer.m_bEnabledToolTips		 = true;
    m_wndZoomer.m_strTipTextForThumbButton = _T("Zoom Slider");
    m_wndZoomer.m_strTipTextForUpButton    = _T("Zoom Out");
    m_wndZoomer.m_strTipTextForDownButton  = _T("Zoom In");

    SubclassChildControls();

    return TRUE;
}

But something is wrong:

1) Even though I said the that I want the position to be in the middle (50) it starts in the left side.

2) in the OnHScroll call, when I look into SCROLLINFO I see that all the values atr zero (min=max=pos=0)

Did I miss anything? Is there something wrong in 2,84?

We cannot confirm this problem. Here is the compiled test application:
