NOTE: You must have a browser that supports JAVA, not just JAVA Script. Sorry, but this feature is currently only available on 32-bit operating systems such as Windows 95/NT, and some Mac and UNIX platforms. If you are using Netscape, you can see if your platform supports JAVA by going to Options/Network Setup/Languages--If "Enable JAVA" is greyed out, then JAVA is not currently supported by your operating system.
