Applet not working in Nescape 6

[Matt Menard]

I have an applet that I created, that currently loads and runs in the
browser that comes with the latest version of Communicator and also
version 5.5 of IE. I downloaded Netscape 6 and installed it. The applet
doesn't load properly in Netscape 6, with the following error message:

java.lang.NullPointerException

It looks like it might have something to do with the plugin code. The
error message doesn't reference any of my applet source, but the (Unknow
Source) could possible mean there's a problem with my code. Any
ideas???
