Bob,
From the stack trace, you aren't using Java 3D 1.3beta1. We did
some major setLive/clearLive cleanup in Java 3D 1.3beta1. If possible
you might want to switch to Java 3D 1.3beta1, and beta2 should be out very
soon. Please send us a test program if the bug still exists in Java 3D1.3
beta1.
thanks,
- Chien Yang.
Java 3D Team.
