Ahhh, i think i see your problem.  When you log out, all processes attached
to your terminal (including the window manager and all your applications)
are killed.  However, Xvnc detaches itself from the terminal and is not
affected.

Workaround: run the vncserver script inside a "screen" session, then type
Ctrl-A followed by D (this will detach 'screen' along with all it's
applications from the terminal).  If you need to kill the session in the
future, you can use screen -R to reconnect to the session, or just use
vncserver -kill.
