[CentOS] resuming FreeNX sessions

I've been running a FreeNX session for several days.

During that time, I have occasionally lost the connect and when I
re-establish the connection, it resumes where I left off and it was
really nice.

Tonight I lost the connection and when I reconnected, it started a new
session but when I run NX Session Administrator application on the
FreeNX server, it still shows the session as 'running'.

I really want to re-connect to my other session as that has the editors
and everything else running and I could terminate it and start over but
I am wondering if there are any tricks that might be had to reconnect to
an existing session (I can see the pid for both the current session and
the session that I would like to connect for example...)

Thanks
