At last check (about 1 year ago), if you run the NeWS classing code through a LaserWriter it works fine. You can look at all the code that is used in /usr/NeWS/lib/NeWS/class.ps. Recently for 1.1 we implemented 'send' in C for performance, but class.ps still contains the original implementaion of send. Greg McLaughlin Sun Microsystems Inc.
