The following code throws a 'List Index Out of bounds(6)'  error. I am trying to change font for all the components on a form and any components within a component.(for example a form containing a pagecontrol which contains several tabsheets, which inturn contain several different components.)
What am I doing wrong?

procedure TSLCCOTForm.FormShow(Sender: TObject);
begin
  if PixelsPerInch <> 96 then
  Iterate(SLCCOTForm);
end;

procedure TSLCCOTForm.Iterate(Contr: TWinControl);
var
i, DesiredSize : integer;
begin
  for i := 0 to Contr.ControlCount -1 do
    begin
       DesiredSize := 8;
       TFooClass(Controls[i]).Font.Name := 'Arial';
       TFooClass(Controls[i]).Font.Size := MulDiv(DesiredSize,96,PixelsPerInch);
       if Contr.Controls[i] is TWinControl then
       Iterate(Contr.Controls[i] as TWinControl);
    end;
end;
