When I compile at home with the latest version of the SDK my applets will not run on the browsers where I work. I get a major version mismatch error. If I compile on the Unix development box here with a much older version of Java then the applets run without error. Apparently applets are not backwardly compataible? If this is true then am I to understand that I have to "dumb down" the applet by compiling it on the oldest version I can find if I want to make it more accessible?
