AIX <--> Solaris X11 Forwarding Problem

[douglas.manton at uk.ibm.com]

I have an X11 application installed on a Solaris 5.7 server.  The server
runs the OpenSSH 2.3.0p1 daemon.  I then SSH to this server from OpenSSH
2.3.0p1 under AIX with X11 forwarding enabled.  I can run X utilities,
such as xclock and xterm, without any problems.  However, the X11
application I require (a Privacy Manager GUI) creates an empty window
frame.

If I telnet from the AIX server to the Sun machine and export the display
then this application works perfectly.  I have tried all combinations of
SSH1, SSH2, compression on and off and different encryption algorithms to
no effect.

Any ideas welcomed.
