   That made a slight change, yet nothing near satisfactory.  Here's 
what's got me baffled now:

In the course of playing with it and testing some different things, I 
noticed that the colors were off the most when I ran gnomemeeting as a 
normal user.  When I run gnomemeeting as root, I've been able to 
actually get the colors satisfactory.  I have no idea what being root 
would have to do with it though.
