Some of the submenus disabled in applet

[Happy S Singh]

My applet has a menu bar and some sub menus.When I access the applet from my systems browser,all sub menus are enabled but when I access same url from some other machine then some of the sub menus are disabled. What can be the issue?

Do I need to do any changes in the settings of the browser?

CODE SNIPPET

private void setupMenus() {
    		getContentPane().add(mainMenuBar, BorderLayout.NORTH);
    		JMenu fileMenu = new JMenu("File");
    		fileMenu.setMnemonic('f');
    		mainMenuBar.add(fileMenu);
    		fileMenu.add(myGenDocViewer.getAction("new_doc")).setMnemonic('n');
    		fileMenu.add(myGenDocViewer.getAction("open_doc")).setMnemonic('o');   //Disabled
    		fileMenu.addSeparator();
    		fileMenu.add(myGenDocViewer.getAction("save_doc")).setMnemonic('s');         		fileMenu.add(myGenDocViewer.getAction("save_as")).setMnemonic('a');
    		fileMenu.addSeparator();
    		fileMenu.add(myGenDocViewer.getAction("export_doc")).setMnemonic('e'); //Disabled

    		fileMenu.add(myGenDocViewer.getAction("print")).setMnemonic('p');
    		fileMenu.add(myGenDocViewer.getAction("print_all"));
    		fileMenu.addSeparator();
    		fileMenu.add(myGenDocViewer.getAction("close_doc")).setMnemonic('c');
    		fileMenu.add(myGenDocViewer.getAction("close_all_doc")).setMnemonic('l');
    		
    		JMenu editMenu = new JMenu("Edit");
    		editMenu.setMnemonic('e');
    		mainMenuBar.add(editMenu);
    		editMenu.add(myGenDocViewer.getAction("undo")).setMnemonic('u');
    		editMenu.add(myGenDocViewer.getAction("redo")).setMnemonic('r');
    		editMenu.addSeparator();
    		editMenu.add(myGenDocViewer.getAction("cut")).setMnemonic('t');
    		editMenu.add(myGenDocViewer.getAction("copy")).setMnemonic('c');
    		editMenu.add(myGenDocViewer.getAction("paste")).setMnemonic('p');

    		editMenu.addSeparator();
    		editMenu.add(myGenDocViewer.getAction("selectAll")).setMnemonic('s');
    		editMenu.add(myGenDocViewer.getAction("deselectAll")).setMnemonic('e');
    		editMenu.add(myGenDocViewer.getAction("selectArea")).setMnemonic('a');
    		editMenu.addSeparator();
    		editMenu.add(myGenDocViewer.getAction("preferences")).setMnemonic('f');
    		
    		JMenu viewMenu = new JMenu("View");
    		viewMenu.setMnemonic('v');
    		mainMenuBar.add(viewMenu);
    		viewMenu.add(myGenDocViewer.getAction("page_first")).setMnemonic('f');
    		viewMenu.add(myGenDocViewer.getAction("page_prev")).setMnemonic('p');
    		viewMenu.add(myGenDocViewer.getAction("page_next")).setMnemonic('n');
    		viewMenu.add(myGenDocViewer.getAction("page_last")).setMnemonic('l');
    		viewMenu.add(myGenDocViewer.getAction("goto_page")).setMnemonic('g');
    		viewMenu.addSeparator();
    		viewMenu.add(myGenDocViewer.getAction("doc_first")).setMnemonic('i');
    		viewMenu.add(myGenDocViewer.getAction("doc_prev")).setMnemonic('r');
    		viewMenu.add(myGenDocViewer.getAction("doc_next")).setMnemonic('e');
    		viewMenu.add(myGenDocViewer.getAction("doc_last")).setMnemonic('s');

    		viewMenu.add(myGenDocViewer.getAction("hide_show")).setMnemonic('a');
    
    		    
    		    	}

Is your Applet signed? You may have a custom policy file on your machine that allows the Applet more than usual access to your system.

Applet is not signed and there is no policy.
