[FreeNX-kNX] can't open terminal window (gnome)

[fdpo1@yahoo.com]

I recently installed freenx-server 0.7.3 on ubuntu 10.04 LTS (gnome) and I'm
accessing it from a windows machine running nx client 3.5.0-7.

It worked wonderfully for a day and then I began having two problems:

1. I can't open a new window -- try to run an xterm (or other window, such as
firefox) and get an error:
"Can't open display: :2000.0"

2. The ctl-alt-T sequence no longer works

Any ideas?  Thanks.
