Yeah I just confirmed this with another user.  We are under Gnome 2.10.  Not 
sure what could cause this.  All gnome applications seem to run fine with 
that key set.

Interesting.  Hope that piece comes into play one day :).

I tried this again as this was my first guess also when reading that 
"clients" were being rejected.  I must have forgot to update gnopernicus 
after making this change of course.  This time I restarted gnopernicus and 
of course the magnification worked :) Oh well at least it is on the 
archives.

Is there a way to use the Xvfb and X session together on the client?  I am 
still trying to understand how X is interpretting all of this.  in AIX we 
accomplish full screen magnification by invoking the vfb and X on screen 0.0 
and 1.0 with a simple -sme flag while starting a session.  I have not found 
an equivelant in Linux, or how to accomplish full screen magnification under 
a remote client.
