Thanks for the tip.  I made those changes to xorg.conf and I still have 
the "stacked" double image (nice description for it, BTW).  So, I'm now 
looking at /etc/ati/amdpcsb file, but I have NO idea how to correlate 
those values to xorg.conf.  What should I be looking for?  Should I post 
that file?

Thanks,
Harry
