On win95, if we change the item of Choice, sometimes will caused an application error, and windows will closed the whole application. Label has the same problem. Following is a test program to check this problem of Choice.

=========================CheckChoice.java======================================
import java.awt.*;
import java.awt.event.*;

public class CheckChoice {
    Choice choice;
    Frame f;
    public static void main(String args[]) {
        new CheckChoice();
    }

    public CheckChoice() {
        f = new Frame();
        choice = new Choice();
        f.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent we) {
               f.dispose();
               System.exit(0);
            }
        });
        f.add(choice);
        f.pack();
        f.setVisible(true);
        addData();
        removeData();
        addData();
        removeData();
    }

    private void addData() {
        String data =
            "\u3000\u3001\u3002\u3003\u3004\u3005\u3006\u3007" +
            "\u3008\u3009\u300a\u300b\u200c\u300d\u3000\u3001" +
            "\u3002\u3003\u3004\u3005\u3006\u3007\u3008\u3009" +
            "\u300a\u300b\u200c\u300d";
        try {
            Thread.sleep(200);
        } catch (Exception ex) {};
        for (int i = 0; i < 50; i ++) {
            choice.addItem(data);
        }
    }

    private void removeData() {
        try {
            Thread.sleep(200);
        } catch (Exception ex) {};
        if (choice.getItemCount() > 0) {
            choice.removeAll();
        }
    }
}
