ASSERT in CXTPDrawHelpers.cpp

   Hi;

I just try to execute our app converted from XTP19.1 to XTP19.3. 
I can't show any property grid because

it crashes in 
BOOL CXTPPropertyGridToolBar::OnWndMsg(UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
    CXTPPropertyGrid* pGrid = DYNAMIC_DOWNCAST(CXTPPropertyGrid, GetParent());
    ASSERT(NULL != pGrid);   <-- ASSERT is fired

    if (pGrid->GetToolTipContext())  <-- Crash
    {
        pGrid->GetToolTipContext()->FilterToolTipMessage(this, message, wParam, lParam);
    }

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

it asserts in CXTPDrawHelpers 
CXTPBufferDCEx::CXTPBufferDCEx(HDC hDestDC, const CRect rcPaint)
    : m_hDestDC(hDestDC)
{
    ASSERT(rcPaint.left <= rcPaint.right);
    ASSERT(rcPaint.top <= rcPaint.bottom);    <-- asserts here all the time (top==1, bottom==-1)

    m_rect = rcPaint;
    Attach(::CreateCompatibleDC(m_hDestDC));
    if (NULL == m_hDC)
        return;

How can we fix this?
