mozilla works fine now. it remembers. but there are other app i noticed will not remember. i'm using gnome, and let's take nautilus. it doesn't remember.
if you type ps -x, do you get sthng like this for nautilus:
nautilus --sm-config-prefix /nautilus-vSifdh/ --sm-client-id 1c0a80005000109990790300000016770003 --screen 0 --no-default-window
The important part would be --sm-client-id, if you don't have that part, it probably means that there is sthng wrong with session management. If you do then I have no real idea.
