Enabling controls on frame on MAC OSX

Question

I'm disbaling and enabling various controls on a frame by following code:
private void disableControls( Component comp, Vector controlList ) {
if ( comp instanceof Container ) {
Component[] children = ( ( Container ) comp ).getComponents();
for ( int i = 0; i < children.length; i++ ) {
disableControls( children, controlList );
if ( comp.isEnabled() && !( comp instanceof Window ) ) {
comp.setEnabled( false );
controlList.add( comp );
*@param controlList
private void enableControls( Vector controlList ) {
Enumeration enum = controlList.elements();
while ( enum.hasMoreElements() ) {
( ( Component ) enum.nextElement() ).setEnabled( true );
But 'enableControls' is not enabling the menu bar items(sometimes). All other controls are enabled.
I checked that call is made to enable menu bar items, but they are not enabled.
This only in case of MAC OS. I'm using MAC OS 10.2.5 and Java version 1.4.1_01
Did anyone know this what could be the problem?
Thanks

This is sometimes caused by Bad Blocks on the Hard Drive.
If 10.7, hold down Command-R at startup, and choose Disk Utility.
If 10.6 or earlier, boot to the Installer/Utilities DVD, answer only the "what language" question and wait for the MenuBar to be drawn. Choose Disk Utility from the Utilities Menu.
Select your Hard drive by Make & Model and check the SMART Status (lower right of the right window). Choose "Repair Disk" . This ONLY examines and repairs the Directory area of the drive, but may improve things a bit. If errors cannot be repaired, you may need a stronger tool, or a new drive.
