Cant set windowmaker as default manager

[Matthew Bettencourt <matt ssc usm edu>]

I am using gnome with windowmaker window as my default manager.  It
seems that I am having a problem making my settings to use windowmaker
stick for more than one session.  I start gnome with gnome-session and
it starts enlightenment.  I go to the control center and set the window
manager to windowmaker and hit o.k., then I am using wm.  I logout and
log back in and I am back in enlightenment.  I go to control center and
it says tha t I am in wm.  I have to switch to enlightenment and then
back and I am set until I log out??  Has anyone else seen this?? 
Thanks
Matt
