Description Vsevolod V Gromov 2021-11-21 23:08:54 EST 
Whenever an empty (data-less) grid control is being hovered over, it would try to FindRow (Tee.Grid.Rows.pas, line 1353)
This subroutine, is throwing AV at line 1378, because there is no Data assigned.
Work-around:
Adding the following at the routine start would fix that, also eliminating the reulst := -1; at the end of this sub.
Result := -1;
if not Assigned(Data) then
  exit;
