Under JSE 1.3, the following code displays a File Chooser Dialog that shows the
files in the directory "C:\JavaPrograms\". Under 1.4, the directory defaults
to "C:\My Documents\", unless you revise the line:
 
     d.setSelectedFile(new File("foobar.txt"));

to the form:

      d.setSelectedFile(new File("C:\JavaPrograms", "foobar.txt"));
