1. Take any sample program of JFileChooser
2. set MotifLookAndFeel by

 UIManager.setLookAndFeel("com.sun.java.swing.plaf.motif.MotifLookAndFeel
");

3. Run it in Solaris 2.6

4. Four button open dialog box will appear for "Open" files. And look at the disabled Help button.

5. We would like to Remove that "Help" button from the layout.

6. This also exists with JDK 1.4.1

Here is my Sample program.. Just complile it and run it..
