Making an applet compatible

Question

I'm working on a webpage, and intentionally used only older Java features for the applet that is much of what makes the page's attraction. (It's an applet to help people learn to remember things better). The applet works fine under appletviewer and netscape, but every button besides "display new list" and "generate new list" only blank the right half of the applet under MSIE 5/Windows, and I'm not sure the applet is stable under MSIE/Mac.
I was wondering if some people here might look at it or tell me what sort of things I might be tripping up on. (Is there something besides validate() that needs to be called so the MicroSoft virtual machine will paint, for instance?) The web page and applet source code, respectively, are at:

Answer 1

Here is the fix for help button:
        private void help()
                actionPanel.add("Center",getTextArea(readFile("help.txt")));   
                }Note that the problem was corrected with the addition of "Center" to the call to actionPanel.add. Upon closer examination, it appears that all such calls must be corrected.
In addition. In the suggested correction that I posted earlier, there are a few changes that you might want to make as shown below:
                             private void chooseListNumber()
                                     actionPanelInternal = new Panel();
                                     actionPanelInternal.setLayout(new FlowLayout());
//                                   actionPanel.add(actionPanelInternal);   //<---------- premature addition
                                     actionPanelInternal.add(getTextArea(HOW_MANY_LIST_ITEMS));
                                     numberOfEnteredItems = new TextField(TEXT_FIELD_COLUMNS);
                                     actionPanelInternal.add(numberOfEnteredItems);
                                     actionPanelInternal.add(new Button(SET_NUMBER_OF_LIST_ITEMS));
                                     actionPanel.add("Center", actionPanelInternal);    //<-------------------added this (V.V.)
                             private void chooseQuizNumber()
                                     actionPanelInternal = new Panel();
                                     actionPanelInternal.setLayout(new FlowLayout());
//                                     actionPanel.add(actionPanelInternal);       //<------- premature addition
                                     actionPanelInternal.add(getTextArea(HOW_MANY_QUIZ_ITEMS));
                                     numberOfEnteredItems = new TextField(TEXT_FIELD_COLUMNS);
                                     actionPanelInternal.add(numberOfEnteredItems);
                                     actionPanelInternal.add(new Button(SET_NUMBER_OF_QUIZ_ITEMS));
                                     actionPanel.add("Center", actionPanelInternal);    //<-------------------------added this (V.V.)
                                     }Got to go get some grub .....please let me know if you need further assistance (I'll check back later)!
