I'm using Sun's JDK 1.3.1 for Windows and Compaq's JDK 1.3.1-1 for Alpha Linux. There are no problems with Linux but Windows doesn't like my code. I started debugging under Windows and realized that the instance of JInternalFrame is created and JDesktopPane's add() method is invoked, but with no result. Any ideas?
