When a JComboBox is added to a JApplet, and the JApplet is displayed in an HTML
frame in Netscape, the JComboBox is unresponsive after the initial selection.
If the JApplet is displayed in an ordinary converted HTML page this does not
occur.
This problem occurs only for Netscape and only on win32. It has been tested with Netscape 4.01, 4.05, and 4.5. The problem does not occur with IE 3.02.
Below is a test case.
-------------------------- JComboBoxExample.java ------------------------------
import javax.swing.*;
import java.awt.*;
public class JComboBoxExample extends JApplet {
public void init() {
getContentPane().setLayout(new FlowLayout());
Object[] letters = {"a", "b", "c"};
JComboBox lettersBox = new JComboBox(letters);
getContentPane().add(lettersBox);
}
}
