/**
 * This small example reproduces the ticket #72 problem.
 * (see http://sourceforge.net/apps/trac/lilith/ticket/72 )
 *
 * Compile executing "javac DialogBug.java",
 * Execute running "java DialogBug"
 *
 * Steps to reproduce:
 * Dismiss both dialogs clicking on "Ok".
 * Press "Ctrl-O". This should print "Open executed" but doesn't.
 * Click on "File" menu.
 * Press "Ctrl-O". Now "Open executed" is printed as expected.
 *
 * Alternatively, execute running "java DialogBug x".
 * Only one dialog will appear.
 * "Ctrl-O" will work immediately after dismissing the dialog.
