    Java errors...

    I have also used all of the different types of browser available to Windows and the Applet works under all of them. It really seems to be a Java problem.
    Any Ideas?

    Did you install the JRE for these browers?

    Yes, I downloaded the most current JRE for Linux just to make sure that I wasn't running an old version. (Same with the MS clients)
    It just seems that there is something looking for classes that should be available, but are not.
