Trouble with Task panel group icons

Hello All,

I created simple SDI application added TaskPanel. Then I want to add groups and group items with icons. I do this way:
    HICON icon1, icon2;
    icon1 = app->LoadIconA(IDI_ICON1);
    icon2 = app->LoadIconA(IDI_ICON2);
    CImageList pImList;
    pImList.Create(16, 16, ILC_COLOR32|ILC_MASK, 0, 1);
    pImList.Add(icon1);
    pImList.Add(icon2);
    m_myTaskPanel.GetImageManager()->SetIcons(pImList, 0, 0, CSize(16, 16));

When I set the icon index to the group elements:
    pGroupWelcome->AddLinkItem(ID_TASKITEM_CONNECTIONS, 1);
It works perfectly.
But when I am trying to set the icon index to the group itself:
    CXTPTaskPanelGroup* pGroupWelcome = m_wndWelcomeTaskPanel.AddGroup(ID_TASKGROUP_WELCOME, 1);
the icon look like large and not streched:
How can I do so that the icon appearance in the group headers looks like such accurately as in the group elements.
Thanks.

thank you. It was helpful
