Shutdown and reboot commands not working

[C. <cch...@no...>]

Hello all,

I am using IceWm 1.2.6-1 with RH 8.0 and Gnome 2.4.

When I do CTRL-ALT-DEL, the CTRL-ALT-DEL MENU appears with all the 
different options :Lock workstation, Logout, Cancel, Restart Icewm, 
Reboot, Shutdown.

The button ICEWm restart works. But the buttons Reboot and Shutdown 
don't. When I clik one of them, I see the Cancel Logout window appear. 
If I clik on Ok, it just closes the active windows but does not launch 
the system shutdown or the system reboot.

In my preferences files I have the following commands :

# Command to shut down the system
ShutdownCommand="sudo shutdown -h now"

# Command to reboot the system
RebootCommand="sudo shutdown -r now"

Sudo is setup correctly as I can use these commands from the command 
line and they launch system halt or reboot.

Any ideas how to make the CTRL-ALT-DEL buttons work ?

Thanks in advance,
