Disabling ZRLE has gotten me up and running. Thanks.

Disable ZRLE encoding in the vncviewer options dialog.
There is a problem with ZRLE that I've been working on, but do
not yet have a solution.
I've seen problems with ZRLE that can cause the HPUX vncviewer
and/or Xvnc to abort.
For those that might be curious, the stack trace from Xvnc is:

Any suggestions on debugging this are welcomed.
