la posicion del form

[roman]

Para la parte de mover los formularios:

interface

type
  TForm1 = class(TForm)
  private
    procedure WMMove(var Message: TWMMove); message WM_MOVE;
  end;

implementation

procedure TForm1.WMMove(var Message: TWMMove);
begin
  inherited;
  if Assigned(Form2) then
  begin
    Form2.Left := Left;
    Form2.Top := Top + Height;
  end;
end;

end.
