Floating Menu Bar (using the java Frame class)

Has anyone created any type of floating menu/toolbar for use with a website?  I am trying to develop one by using the java Frame class and adding a Menubar to it.  I am trying open up different HTML pages when I click on a particular menu item.  It will open an HTML page once, but after that, it no longer will open any HTML pages.  Does anyone know what the problem could be?  If so, do you know how I could correct it?

This is the code for the Frame which contains the menubar and toolbar:

                    dispose();

                if (c instanceof Frame)
                    break;

This is expected to happen because when you go to some other page, the page containing your applet is no longer there (even though your applet is running). So the AppletContext (the doucment in which the applet is running) is no longer valid and calling showDocument on it would not do anything. A probable solution to this problem is that you always keep your applet document in the browser, so when you call showDocument, you show that doucment in a new browser window -

showDocument (URL, "_blank") ;
