So I've tested the web-site in Firefox, Internet Explorer and Chrome. The Java applets work in all of them (sometimes after upgrading Java and trusting the site), but in Chrome the applet area is bigger than it should be. How is it we're in 2012 and we still have compatibility issues with browsers? I guess with unfettered capitalism, you take the good with the bad!
I don't know if it works on Apple's Safari. I hope so!
