Hi Dennis-

When you say blank, do you mean that it is grey?  Does it change
if you resize the window?

It appears that the X Windows emulator you are using on 
Windows does not support the GLX extensions which are needed
for Java 3D.  What X client are you trying to use?  Can you find 
out if it supports GLX?
