JTextField not responding when app jar'd

Question

I have a few JTextFields on a JWindow which was working when I was designing the app. I was using VAJ3.5. Once I jar'd with jdk1.3.1 the first textfield would respond when I "java -jar My.jar" and the 2nd would only gain focus when i would click to another program and I would come back to the jar. And if I double clicked then both texts would not respond. I then changed to a JDialog, and everything works fine now.
I would rather use JWindow but im at a loss to explain why this would happen. Can anyone shed some light?
Thank you for your time

Try this basic troubleshooting fix:
1 - delete the IDVD preference file, com.apple.iDVD.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete IDVD'S cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iDVD folder.
3 - launch IDVD and try again.
NOTE: In Lion, Mountain Lion and Mavericks the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and press the Return key - 10.7: Un-hide the User Library folder.
If you're running Mavericks, 10.9,  go to your Home folder and use the View ➙ Show View Options menu to bring the this window:
It the above doesn't help Boot into Safe Mode, Mac OS X: Starting up in Safe Mode, and try iDVD there.  Then reboot normally and try again.
