Just has text on the page. I assume there is a window on the page somewhere that's supposed to be the game, but I can't tell as there is no big square space open.
I'm using Firefox 3.6 and IE 7 but I think IE is using some old version of Java. I think our time card program at work uses Microsoft's Java so I had to keep the browser set that way...
I have several versions installed. Hmm, I may have stumbled into some political mumbo jumbo
Firefox is disabling the java plugin
Java 2 Plugin v1.5_00-1.6_99. Reason: These versions of the Java plugin are no longer supported by Oracle and cause severe stability issues for Firefox 3.6 and later (see bug 634639)

I believe Microsoft's Java stopped somewhere around JDK 1.1.4, but the Rules Roundup applet should actually work with Java 1.1. I just had a look and the class files are actually version 45, which is 1.1 compatible. I don't know if the applet works with Microsoft's JVM, though, and I suppose it's possible you have an older version of that as well.
But if you installed the latest Sun^H^H^HOracle JVM for Firefox, then that would almost certainly work.
