[FreeNX-kNX] custom X session and suspend

[Marcin Bukat]

I have small question. I'm running custom session (fluxbox based) with 
freeNX. Everything is ok if I run this in 'window mode'. I can click 
'close button'  on this window and dialog asking to suspend/terminate 
the session appears. But if run in fullscreen mode I can't end session 
(selecting 'exit' in fluxbox's menu doesn't work). What should I invoke 
to see suspend/terminate dialogbox?

regards
Marcin
