Win32: Choice with too many objects to display, should have vertical scrollbar

Win32: A Choice control with more items than can be displayed in its list should
have a vertical scrollbar in the list.

Steps to reproduce:
Compile and run the attached code
<Click> on the Choice open list button
// Note: there are 21 items in the list, there should be a scrollbar if all 21 are not
    visible.

import java.awt.*;
import java.applet.Applet;

public class ChoiceTest extends Applet
{
   private Choice choice;
   private int counter = 0;
   public ChoiceTest()
   {
      setLayout( new BorderLayout() );
      add("North", new ChoiceTestCP(this) );
      add("Center", choice = new Choice() );
      choice.addItem("[none]");
      // fill choice list
      for(int i = 0; i < 20; ++i)
         addItem();
   }

   public void init()
   {
      resize(400, 200);
   }

   public void addItem()
   {
      choice.addItem( Integer.toString( ++counter ) );
   }

   public static void main(String argv[])
   {
      AppletFrame.startApplet("ChoiceTest", "Choice Test", argv);
   }
}


class ChoiceTestCP extends Panel
{
   private ChoiceTest applet;
   private final String ADD_ITEM = "Add Item";
   private final String ADD_ITEMS = "Add Items";
   private int counter;
   private TextField field;

   public ChoiceTestCP(ChoiceTest ct)
   {
      applet = ct;
      add( new Label("Count") );
      add( field = new TextField( "1", 10 ) );
      add( new Button(ADD_ITEMS) );
   }

   public boolean action(Event evt, Object obj)
   {

      if( evt.target instanceof Button )
      {
         String label = obj.toString();
         if( label.equals(ADD_ITEM) )
         {
            applet.addItem();
         }
         else if( label.equals(ADD_ITEMS) )
         {
            int limit = Integer.parseInt( field.getText().trim() );
            for( int i = 0; i < limit; ++i )
               applet.addItem();
         }
         else
            return false;

         return true;
         

      }
      else
         return super.action(evt, obj);
   }
