Adding radio buttons to an applet

Question

Hi
Just wondering if anyone else has had the same problem?
i'm using the following which seems to work when run in Internet Explorer but it doesn't want to display in Opera!?!
     private CheckboxGroup radioGroup = new CheckboxGroup();
     private Checkbox radio1 = new Checkbox("Int", radioGroup, true);
          public void init(){
          add(radio1);}Any ideas of why?
Cheers

why don't you use JRadioButton, compile and run this:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class BackGroundTest extends JFrame implements ActionListener{
JRadioButton patternBrushedBlue=new JRadioButton("Brushed Blue",true);
JRadioButton patternBlueWaves=new JRadioButton("Blue Waves");
JRadioButton patternBlackThatch=new JRadioButton("Black Thatch");
JRadioButton patternMetalWall=new JRadioButton("Metal Wall");
JRadioButton patternCoffeeBean= new JRadioButton("Coffee Bean");
JRadioButton patternPrairieWind= new JRadioButton("Prairie Wind");
JRadioButton patternBlackRock = new JRadioButton("Black Rock");
JRadioButton patternStainless = new JRadioButton("Stainless");
JRadioButton patternStars = new JRadioButton("Stars");
JRadioButton patternGrayStone = new JRadioButton("Gray Stone");
JRadioButton patternGreenStone = new JRadioButton("Green Stone");
JRadioButton patternOcean = new JRadioButton("Ocean");
JRadioButton patternIron = new JRadioButton("Iron");
JTextField wallBox = new JTextField(20);
String wallPaper;
public BackGroundTest(){
getContentPane().setLayout(new BorderLayout());
JPanel topPanel = new JPanel(new GridLayout(1,6));
JPanel bottomPanel = new JPanel(new GridLayout(1,7));
ButtonGroup b = new ButtonGroup();
b.add(patternMetalWall);
b.add(patternBrushedBlue);

b.add(patternIron);
b.add(patternStars);
b.add(patternGrayStone);

b.add(patternOcean);
patternBlueWaves.addActionListener(this);
