Bug in TChart Pro 3.0b/Arrows/Zoom

Maybe this is a bug in TeeChart Pro 3.0b.

I have a TChart with a TArrowSeries. If I draw a single arrow
and then zoom several times using the mouse, I get an error message like
"wrong floating point operation" (I translate this from "opration flottante
incorrecte").

See the code fragment below for the creation of the arrow.

Any ideas?
Thanks

type
  TForm1 = class(TForm)
    Chart1: TChart;
    Series2: TArrowSeries;
    procedure FormCreate(Sender: TObject);
  private
  public
  end;

var
  Form1: TForm1;

implementation

{$R *.DFM}

procedure TForm1.FormCreate(Sender: TObject);
begin
 Series2.Clear ;
 Series2.AddArrow(0.0,0.0,1.0,1.0,'',clYellow) ;
end;
