Dude... I went through so many configs over the last 4 days you have no 
idea! :-)

So I don't know what log/config pair you want me to post. I *DO* have a 
config remaining that I named as it does the duplicate desktop thing I 
think... I am attaching it.

Also... patching X is not something I will be doing with this 
installation. It's a rhel4 beta 2 install that I am using to develop 
updates for Red Hat courseware so it has to stay as it is for now. So 
between that fact and the additional fact that I cannot code my way out 
of a wet paper sack (admin here and proud of it :-) it's not a good idea 
to start hacking at this install. Useful patches that fix brokenness 
should probably be thrust in Mike Harris direction... :-)

Lastly... replying to the list is good enough for me... replying to the 
list and cc'ing me or vice versa is a bit of a nuisance...

txs!
