i'm using JDK1.2.2, NT4 sp5

The problem that i'd appreciate some help on is:

Creating a JInternalFrame with the constructor: new JInternalFrame(String
title, boolean resizeable, boolean closeable, boolean maximizable, boolean
iconifiable )

with the default metal LaF works fine . . .the buttons do not appear on the
title bar as expected.

However, when the LaF is changed to CDE/motif or Windows, the title bar
buttons appear and work.  I know I can override these close events, but
wondered why the
buttons appear when I don't want them to.

here's how I change the LaF

        public void setLaF() {
            try {
             UIManager.setLookAndFeel(laFClassName);
                Runnable runnable = new Runnable() {
            public void run() {
                  SwingUtilities.updateComponentTreeUI(--Top level
Container--);
                    }
               };
                SwingUtilities.invokeLater(runnable);
            }
            catch (UnsupportedLookAndFeelException
ulafe){System.out.println(ulafe);}
            catch (IllegalAccessException iae) {System.out.println(iae);}
            catch (InstantiationException ie2) {System.out.println(ie);}
            catch (ClassNotFoundException cnfe) {System.out.println(cnfe);}
        }

any ideas . . .?

thanks in advance Paul Turner
