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
Thanks in advance.
