Beryl stopped working

I am running xfce4 and beryl 0.2.0 SVN on Archlinux (on my T42). Beryl is quite buggy at the best of times. The latest problem I had was berly not starting at all. I seemed to be stuck in xfce4. A quick look at the arch forums and someone suggested making sure the 'Window Decorations' plugin is selected (It's under 'Visual Effects'). It was on my setup, but I tried deselected it and selecting it again, and magically it's all working again. Weird.
