Window Manager

[Quentin Decavel <qdecavel@wanadoo.fr>]

Hi again,

First of all, sorry for my previous message, I was thinking of 
debian-user-french when I sent it :-/

I have just updated my Debian distribution via apt-get, and especially 
I have updated Gnome to the 2.4 version. Rebooting showed no problem, 
but I had an error message about the window manager.

When I open a new window, it goes to the upper left side of the screen, 
and I never have the possibility to resize it or move it with the 
mouse. I suppose my window manager is not set up (at all ?), but how to 
do it ? I searched in the Gnome configuration center, but I didn't 
find...

Thanks in advance.

Quentin
