Environment:
WindowsNT 4, service pack 3
jre1.1.6
Swing 1.0.1
Pentium 300MH 128 MB RAM

I have an application which includes JTextFields. When I launch the
application the JTextFileds accepts focus when I click inside their
area, but after I do some operations like changing some menu item state
or click on some JButton to initiate some action, all the JTextFields in
the application stop accepting focus.

This application works just fine using jre1.1.5.
