I can't be bothered to do it at the moment.

Because the applet doesn't recognize that it does.

How do you figure? It asks for Java 1.5+, and 1.6 is certainly above 1.5. -- Lew

Doesn't that meet the requirement of being at least 1.5? This whole non-problem makes no sense to me, but then I'm not familiar with applets. Do applets complain when you have a more recent version of Java when they specify a minimum version? -- Lew

I think I'm beginning to see what I'm missing. Apparently what Lars left out is that the applet refuses to run and complains that his version is not recent enough. The "applet refuses to run" part is what I didn't see in his post. Do I have that right? -- Lew |
