   Hello

This control works fine until you create this control with flag LBS_EXTENDEDSEL!

Is this known?
In this case, this flag should be removed in Create(...). So it will be more clearly that this flag is not supported.

If it a unknown problem:
- You cannot move items more than 2 levels up or down.
- If you use it with flag LBS_XT_BROWSE, following code is executed

void CXTEditListBox::OnItemBrowse()
{
    m_nIndex = GetCurSel(); // Current index.
    int nNewIndex = m_nIndex + 1; // New index.

    // If there is a valid selection made, and the
    // selection is not the last item and...
    if ((m_nIndex != LB_ERR) && (nNewIndex < GetCount()))
    {
        // Save the string for the current
        // selection.
        CString strCurItem;
        GetText(m_nIndex, strCurItem);

        // Save any item data.
        DWORD_PTR dwCurData = GetItemData(m_nIndex);

        // Remove both the new and current
        // index items...
        DeleteString(m_nIndex);

        // then swap and re-insert them into
        // the list box.
        InsertString(nNewIndex, strCurItem);

        // Restore any item data.
        SetItemData(nNewIndex, dwCurData);

        // Select the item at the new index.
        SetCurSel(nNewIndex);
    }
    // Set the focus back to the listbox.
    SetFocus();

    CWnd* pOwner = GetOwner();
    ASSERT(pOwner);

    // Send notification to owner.
    if (pOwner) pOwner->SendMessage( WM_COMMAND, MAKEWPARAM(GetDlgCtrlID(),
        LBN_XT_ONBROWSE), (LPARAM)m_hWnd );
}

What should this code doing?? It is not necessary to swap items. In normal mode, this code don't reach.
