Swati,
Once I finish updating the textfiles that contain the questions and explanations I shall put the standalone version up for download. Since that is an executable jar file it will use the VM that came with your JDK.
If you open the
Java Console(open View & Java Console in the menubar of your browser) you can see the dump from the VM. It will show you a series of ClassNotFoundExceptions. This is because the older browsers dont have most of the classes that you use in JDK1.2 or higher.
I shall have the standalone version ready in a couple of days.
