/** On Solaris Sparc 2.6, HeavyWeight JPopupMenus obscure other windows.
  *
  * Step 1: Run the Application.
  * Step 2: Adjust the main window size so that Menu 2 is NOT
  * contained by the main window.
  * Step 3: Click on Menu 2 and move your mouse to another part
  * of the screen, leaving Menu 2 up. Move another
  * window (a terminal window or something) over this
  * application. Note that the Menu 2 window is ON TOP
  * of your terminal emulator.
