Arrow problem

 Hello ROOTers,

  I cannot reset the arrow size in the enclosed macro. When I run 
  this macro the arrow is missing its head. It happens in root 2.23/08
  under SunOS5.7.

  Thank you with regards,

    Michal Lijowski


{

   TCanvas *c1 = new TCanvas("c1", "c1", 800, 600);
   TH2F *h2r = new TH2F("h2r", "test", 2, -30.0, 300.0, 2, -30.0, 300.0);
   h2r -> Draw();

   TArrow *arr = new TArrow();
   arr -> SetArrowSize(0.05);
   arr -> DrawArrow(190.0, 30.0, 195.0, 30.0,);
   cout << "  Arr Size  " << arr -> GetArrowSize() << endl;

   c1 -> Update();
}
