For some reason, the gnome control center doesn't want me to configure any sawfish aspects. When I click on any of the sawfish configuration options, the left pane displays nothing, and eventually, the entire app freezes and has to be killed.
Another thing I noticed is that the control center often thinks that Enlightenment is the default window manager, even though it is sawfish that is actually running. I don't know if this has anything to with the previous problem, but I thought I would mention it. -Rob
