Unable to run administrative applications from Xnest

[redhatdude at bellsouth.net]

Hi,
This is a little weird. I am unable to run administrative  
applications from Xnest. What I do is ssh -X user at linuxbox and once  
there I launch Xnest :2 -geometry 800x600 -query localhost
I can't do anything that requires me to enter my root password. The  
applications won't start after I click ok. I then logged in as root  
and did the same thing in KDE within the user root environment. Same  
thing. Administrative applications won't start. If I vnc into the  
machine everything works as expected. If I forward X and instead of  
launching Xnest I launch startkde then everything works as expected.  
It's only when I'm in Xnest that this happens.
Can anyone help?
Thanks,
Ellier
