[FreeNX-kNX] Attaching to a session from multiple locations

[Michael Hirsch]

I have a linux box running freenx.  I can connect to it from home, or
from work, but I get different sessions.  I'd like to be able to
connect from home and get the same session I had from work.

When I connect, I can see the other session, but it is greyed out and
not available for me to choose.

What is causing this?  How can I pick up the same session from
different locations?

Thanks,

Michael
