Karsten,
Thanks for the valuable feedback. We'll go thro. the list and get
back to you ASAP.
It is a short beta. We would like to have all feedback incorporated
within the next four weeks, so that we may quickly move to FCS. Any test
program that reproduce bug is greatly appreicated.
thanks,
Chien Yang.
Java 3D Team.
