Hi Bill,
OK, I understand what you are trying to do now.
To answer your original question - I believe that once you have
succesfully set the look and feel, then it should remain in effect for the remainder of your applications life.
Personally I didn't set the look and feel. That way the user could use a different look and feel if they really wanted to, but by default it would be the
Java Look and Feel.
Regards, Andrew
