I haen't played with this much, but....
There is a directory in Xj3D
distribution(http://www.hypermultimedia.com/Xj3D/getstart.htm) called
Vrmlet. It has an example of an Applet. My hopes is that it doesn't
have the same problems... try it out, if you get the same error then
I'll take a peak at it.
