{
	SjCol* currCol;

	// verify stored anchor
	if( m_selAnchorColIndex != -1 )
	{
		currCol = GetMaskedCol(m_selAnchorColIndex);
		if( currCol == NULL )
		{
			m_selAnchorColIndex = -1; // recalculate anchor - this is no error!
		}
		else
		{
			if(  m_selAnchorRowIndex<0 || m_selAnchorRowIndex>=currCol->m_rowCount
			        || !currCol->m_rows[m_selAnchorRowIndex]->IsSelected() )

				m_selAnchorColIndex = -1; // recalculate anchor - this is no error!
			}
			delete currCol;
		}
	}

	// recalculate anchor if needed
