        // was running, I tried do delete 3 records from within the grid. Deletion caused a SeekCursor, which made a
        // m_pSeekCursor->moveRelative and a m_pSeekCursor->getPosition.
        // Unfortunately the first call caused a propertyChanged(RECORDCOUNT) which resulted in a repaint of the
        // navigation bar and the grid. The latter itself will result in SeekRow calls. So after (successfully) returning
        // from the moveRelative the getPosition returns an invalid value. And so the SeekCursor fails.
        // In the consequence ALL parts of code where two calls to the seek cursor are done, while the second call _relies_ on
