Gnome doesn't save session

[Axel Minck <minck@eleves.enpc.fr>]

Hi,

I have a little problem with gnome 1.4 : as user, X environment starts 
with both IceWM and Gnome panels and with IceWM window manager. Yet, i 
have configured the Window Manager section to use Sawfish. Moreover 
nothing is saved at the end of my session (backgroung, icons of 
panel,...) and i have to set everything again when i restart X.
As root, i don't have this problem
I checked authorizations of files in my user's directory, but i didn't 
solved this problem because i don't know which file is used to stored my 
personal settings.
Any ideas
Thanks by advance

Axel
