Thanks, that worked!

I'm not really sure why though....  I've been through the xauth
section on trusted vs. untrusted, and skimmed the X11 SECURITY
extension specification.

Using ssh -X works on my 5.3BETA4 system from 10/2004.  It's running
an Xorg 6.7 server.

Is this the result of an X change, and ssh change, or a butterfly
flapping it's wings over Brazil?

Thanks again for the help!
