Applets don't work the same in all browsers. I haven't found a good source of tests or documentation on this. Hopefully this site will fill that gap.
Frankly I'd avoid applets if I could. They don't work on mobile browsers, and with the recent security issues more and more people have them disabled. But sometimes applets are a necessary evil.
