Problem running XFwm4

[Ted Clark]

Hello all,

This is a problem that I initially posted on the Source Forge XFce forum 
because I was unable to access this site last week.

I have a clean base install of Debian Woody which I have dist-upgraded 
to unstable.  I subsequently installed the base X window system via 
apt-get along with the 20021117 CVS packages of xfwm4 and xfce4.  My 
~/.xinitrc file looks like this:

xfwm4 &
sleep 2
exec xfce4

This gives me a dialog box that telling me that xfce4 needs a window 
manager that supports extended window manager hints.  Execing an xterm 
instead of xfce4 gives me an xterm window without a border, so it seems 
that xfwm4 is not starting.

Diffing the output from 'dpkg -l' after installing xfwm4 and xfce4 looks 
like this:

Any ideas on how I might proceed with this?  Am I missing a required 
package?  I've been a Debian user for all of one week now, so I might be 
doing something really dumb! :-)

Thanks,
