Forgot to add in my last message: are you su'd to another user when trying to 
fire up an app?  The problem is with your session authentication -- you can 
see it in action if you do the following:

log into X as your regular user
open the xterm of your choice
su to root
execute mozilla
ta-da!  X should complain.

... the problem being, root is asking the X server to display a window to a 
session which root does not own.
