Thanks go to Dave Johnson, Mike Smedberg and Corne Beerse for several
suggestions regarding different ways to launch Xvnc sessions but what
finally made it work was updating to the current CDE patches for HP-UX 11.11
and rebooting the server. The Xvnc sessions now restart when the users logs
off just like they're supposed to. Along the way I updated to Xvnc v4.0
from www.realvnc.com but it also works with the old v3.3.3r1 binaries.
Cheers, Tom
