Sorry, EvanD, but it's not a proof. I could show you exactly the same picture from my Firefox 3.5.11 (it means only that Java 6 update 21 was installed on your PC).
Have you tested Firefox 3.6.8 and Java on such sites?
http://www.javatester.org/ or http://www.java.com/...help/testvm.xml
You're right, with Firefox 3.6.8 on javatester.org, the applet test fails. However, JRE u21 works on all the sites I normally go to including the Flash test which, from previous msfn.org discussions, I was led to believe requires some form of a java applet to work (isn't that why we uncheck "new java plugin?").
For IE6, JRE u21 does work. See figure. It does not work for Seamonkey 1.1.19.
I plan to keep JRE u21 for a while until I run in to a practical problem. When that happens, I'll revert back to u20.
Thanks for alerting me to try the direct Java applet test; at least I now know there's a potential problem lurking ahead. Is there something I should be wary of?
