If you have a browser other than Mosaic, you should be able to view most of the content of this site. Netscape version 3 or Internet Explorer version 2 should be sufficient.
If you are having problems with viewing the java applets, you need a browser which supports Java 1.1. The most stable browsers are Internet Explorer 4.01 SP 1 and Netscape Navigator 4.08 for Windows. There is also a simple update for IE4 to update the java engine(MS Java update to build 2925).
If all else fails, please email Chris Stauffer with a bug report.
