Hello,
    We recently upgraded from toolkitpro 9.6 to 13.1 and discovered that the tooltip over a CXTPTabControl derived control does not appear anymore in some situation. The way to reproduce the problem is to put another application over our app (e.g. notepad) and clicking on application caption + quick mouse moving over tabcontrol and stop there, waiting for tooltip but nothing happens -tooltip does not appear. Moving again mouse over other controls and returning back over our tabcontrol works fine. Also the mouse moving must be done quickly < 0.5 sec.

we are using some overides such as:

BOOL CMyXTPTabControl::OnWndMsg(UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
    MSG msg;
    msg.wParam = wParam;
    msg.lParam = lParam;
    msg.message = message;
    msg.hwnd = m_hWnd;
    GetCursorPos(&msg.pt);

    // Tooltips notification.
    FilterToolTipMessage(&msg);

    return __super::OnWndMsg(message, wParam, lParam, pResult);
}

INT_PTR CMyXTPTabControl::OnToolHitTest(CPoint point, TOOLINFO* pTI) const
{
    return PerformToolHitTest(m_hWnd, point, pTI);
}

Also checked code against version 1331 and same behaviour.
