[K12OSN] Experience at Glenburn this week.

[Lewis Holcroft]

Shane,

Its sounds like this was a great success. As far as IceWM goes. I 
recently changed a production environment from gnome to IceWM. While 
the end users have noticed that some menu options are different, it was 
much easier to set up menu's specific to job function. It's so.... much 
faster, easier to configure and theme (if you want to go to those 
lengths) that I can't this of a reason to use gnome.

I spent hours trying to use gconf to restrict menus, and trying to undo 
it was a nightmare. 45 minutes after looking at IceWM and we were all 
set.
