If I compile this code, no internal frames are appearing.
Did you run that app?

RE: Problems creating internal frames with Swing
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?
Thanks,
Steve.
