Strange FNC Grid moving to next row after updating current row

I have found a strange behavior with the FNC Grid connected to a grid adapter.
If you edit a cell then use the dbnavigator to go to the next or previous row, the cell gets empty.

Hi,

You can apply this code as a workaround to stop editing when navigating with the Navigator:

procedure TForm130.DBNavigator1BeforeAction(Sender: TObject;
  Button: TNavigateBtn);
begin
  TMSFNCGrid1.StopEdit;
end;

Thanks
