The grid tooltip window is using the cell text colour, so when a cell has white text (on a dark background) the tooltip text is not visable> It is shown as white on the standard toolitp cream background. How do I get the tooltip text to always be black?

Thank you for reporting the bug. To fix it, please open the CExtGridCell::OnPaintExpandedContent() method and find the following line:

COLORREF clrBk = wndGrid.OnSiwGetSysColor( COLOR_INFOBK );
Then replace it with the following code:
COLORREF clrBk =
                        OnQueryBackColor(
                                   wndGrid,
                                   picd.m_dc,
                                   htInfo.m_nVisibleColNo,
                                   htInfo.m_nVisibleRowNo,
                                   htInfo.m_nColNo,
                                   htInfo.m_nRowNo,
                                   htInfo.GetInnerOuterTypeOfColumn(),
                                   htInfo.GetInnerOuterTypeOfRow(),
                                   htInfo.m_dwAreaFlags,
                                   0L //dwHelperPaintFlags
                                   );
            if( clrBk == COLORREF(-1L) )
                        clrBk = wndGrid.OnSiwGetSysColor( COLOR_INFOBK );
