Multiple Linux JComboBox drops in the same position

Question

Following program create two similar JComboBox dropdown, and in Linux, when it runs, it works weirdly.
If I first click first dropdown (s1), then later when I click second one (s2), dropdown part still appears under the first component.
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class JBugClass {
     public static void main(String[] args) {
          JFrame frame = new JFrame("BugClass AWT version");
          Container pane = frame.getContentPane();
          String[] items = { "Item 1", "Item 2", "Item 3" };
          JComboBox s1 = new JComboBox(items);
          JComboBox s2 = new JComboBox(items);
          JButton wx = new JButton("QUIT");
          wx.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent ae) {
                    System.exit(0);
          pane.setLayout(new FlowLayout(FlowLayout.LEFT));
          pane.add(s1);
          pane.add(s2);
          pane.add(wx);
          frame.pack();
          frame.setVisible(true);
}I created separated string arrays for s1 and s2, but position is still incorrect. It works completely fine in Windows. I am now suspecting that this is a bug of Linux J2SE1.4.0. Does anyone know any workaround?

All of the features you're asking for are very easy to add and control in LabVIEW once you know what you're looking for. To show the Front Panel of a SubVI, open the VI and navigate to its "Customize Window Appearance" window (this is in File>VI Properties, select Category: Window Appearance, then click "Customize"). Check the "Show Front Panel when called" checkbox.
However, there are quite a few other properties you'll likely want to edit as well, so it would be best to review the LabVIEW Topic: "Customize Window Appearance Dialog Box".
In your main VI, put the SubVI in the True case of a Case Structure, then connect your button to the selector terminal. The more complex behavior your asking for can be achieved using multiple case structures.
