Multi-window problems on remote clients

[Jim Scheef]

Hello,

Wow, I actually get an opprotunity to contribute!

I use Xdmcp with -multiwindow and it works fine. You just need to use the
Xnest client/server to provide a 'window' for the remote machine. The
command... 

$ Xnest :1 -query <host>

gets it going.
