            This test is to verify JFileChooser on Windows and Metal LAF.
            Use the "Change LaF" menu to switch between the 2 LaF
            and verify the following.

            a. Change view mode to "Details"
            b. Check that 4 columns appear: Name, Size, Type and Date Modified
            c. Change current directory by pressing any available subdirectory
               or by pressing button "Up One Level".
            d. Check that still four columns exist.

            Change LaF and repeat the steps a-d.
            If all conditions are true press PASS, else FAIL.
