A couple of people have reported difficulties trying to make the applet run in their browsers... This is what we did to fix the problem:
1. Check which version of the Java Virtual Machine (JVM) you're currently using. This can be done several ways, the simplest way I know is to use the following link:

2. Upgrade your JVM (if needed). Apparently, my program does not work with Microsoft's version of the JVM or with very old versions (Java 1.1 or older). You can install the latest version from Sun Microsystems by clicking on the "Free Download" link at the top right of the same web page just mentioned above.
3. After installing, the Java Plug-in provided by Sun might need to be configured to run with your browser. To do this, open your Control Panel. Look for the Java Plug-in icon and open it. A small window should appear. Click on the "Browser" tab. Select the browser you want to use and then click on the Apply button.
That's it! After going through the above ordeal, you should be able to run the MazeMarathon program without anymore problems...
