JPanel not displaying in Windows

Question

I have a window displaying a panel and some buttons. I installed the application on Solaris and Windows. On Solaris, it displays fine every time. On Widows, it displays the first time I bring up the application but the panel does not display when I close it and bring it back up. Has anyone seen this before. I've put some debugging statements in, but I have no idea where to start looking.
Thanks,
Josh

Here is the code that sets up the panel:
// Initialize and GUI implementation
private void jbInit() throws Exception {
try{
logger.fine("AudioEditPanel jbInit");
this.setLayout(new BorderLayout());
m_audioIcon = new ImageIcon(dataDir + File.separator + m_sAlertIcon);
TitledBorder curSettingBorder = new TitledBorder(m_sCurSetting);
TitledBorder soundBorder = new TitledBorder(m_sSound);
m_editPanel.setLayout(new BorderLayout());
// Create "Restore Default" button
m_defaultButton.setText("Restore Default");
m_defaultButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
     defaultButton_actionPerformed(e);
m_currentPanel.setLayout(new BorderLayout());
m_currentPanel.setBorder(curSettingBorder);
m_currentPanel.setPreferredSize(new Dimension(155, 165));
// Create customized tabel model
AudioTableModel tableModel = new AudioTableModel();
curTable = new JTable(tableModel);
//Set up column sizes.
initColumnSizes(curTable, tableModel);
// Only allows single selection
curTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
curTable.setBorder(BorderFactory.createLoweredBevelBorder());
curTable.setColumnSelectionAllowed(false);
curTable.getTableHeader().setReorderingAllowed(false);
setUpWavEditor(curTable);
//Fiddle with the Preview column's cell editors/renderers.
setUpPreviewColumn(curTable.getColumnModel().getColumn(preview_column));
// Add filter for the File Choose, so only Sound (*.wav) file
// can be used.
fc.addChoosableFileFilter(new WavFilter());
fc.setAcceptAllFileFilterUsed(false);
fc.setFileSelectionMode(JFileChooser.FILES_ONLY);
if (m_sDesDir != "") {
File wav_dir = new File(m_sDesDir);
fc.setCurrentDirectory(wav_dir);
fc.setDialogTitle("List of audio files");
m_assignPanel.setLayout(gridBagLayout1);
m_assignPanel.setBorder(soundBorder);
// "Selected Sound" label
SelectSoundLabel.setFont(new java.awt.Font("Dialog", 0, 10));
SelectSoundLabel.setForeground(Color.black);
SelectSoundLabel.setText("Selected Sound:");
//Click Browse button will pop up file chooser
browseButton.setActionCommand("Browse");
browseButton.setText("Browse");
browseButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
     browseButton_actionPerformed(e);
//Click preview button will play the sound defined in the sound text area
previewButton.setIcon(m_audioIcon);
previewButton.setMargin(new Insets(0, 0, 0, 0));
previewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
     previewButton_actionPerformed(e);
// selected sound text field.
sSoundText.setBorder(BorderFactory.createLoweredBevelBorder());
sSoundText.addActionListener(new ActionListener() {
public void actionPerformed (ActionEvent e) {
sSoundText_actionPerformed(e);
// "Preview" label
previewTextArea.setFont(new java.awt.Font("Dialog", 0, 10));
previewTextArea.setText("Preview");
previewTextArea.setForeground(Color.black);
// Use GridBag layout to put the components in the proper position
m_defaultPanel.add(m_defaultButton, BorderLayout.CENTER);
m_editPanel.add(m_assignPanel, BorderLayout.SOUTH);
m_assignPanel.add(browseButton, new GridBagConstraints(0, 2, 1, 1, 0.0, 0.0,GridBagConstraints.SOUTHEAST, GridBagConstraints.NONE, new Insets(0, 0, 0, 0), 2, 0));
m_assignPanel.add(previewButton, new GridBagConstraints(1, 1, 1, 1, 0.0, 0.0,GridBagConstraints.NORTHEAST, GridBagConstraints.NONE, new Insets(0, 0, 0, 0), 0, 2));
m_assignPanel.add(previewTextArea, new GridBagConstraints(1, 0, 1, 1, 0.0, 0.0,GridBagConstraints.CENTER, GridBagConstraints.NONE, new Insets(0, 0, 0, 0), 0, 0));
m_assignPanel.add(sSoundText, new GridBagConstraints(0, 1, 1, 1, 0.0, 0.0,GridBagConstraints.NORTHWEST, GridBagConstraints.NONE, new Insets(0, 0, 0, 3), 257, 2));
m_assignPanel.add(SelectSoundLabel, new GridBagConstraints(0, 0, 1, 1, 0.0, 0.0,GridBagConstraints.WEST, GridBagConstraints.NONE, new Insets(3, 0, 6, 0), 6, 0));
m_curScrollPanel.getViewport().add(curTable, BorderLayout.CENTER);
m_currentPanel.add(m_curScrollPanel, BorderLayout.CENTER);
m_currentPanel.add(m_defaultPanel, BorderLayout.SOUTH);
m_editPanel.add(m_currentPanel, BorderLayout.NORTH);
m_tabbedPane.addTab(m_sAudioSetting, m_editPanel);
this.add(m_tabbedPane, BorderLayout.CENTER);
checkAudioPrefs();
}catch(Exception e){
e.printStackTrace();
System.out.println(e.getMessage());
