Yes, I see. Also the needed cursor images are not bundled with JNC 1.1.

Well, that's unfortunately not a simple problem such as a missing class. 
This is just a good reason why AWT/Swing support is still experimental.

Thanks for that! I always appreciate AWT/Swing examples since I only 
have some minor small ones. I'll see to it that it will work in JNC 1.2.
