Hello,
So far, I really like Fences. It does make my desktop more organized! Ok, as for the bug...
If I try any right click options as suggested by the customize fences dialogue, fence related right click options fail to appear in the contextual menu. I know this is going to be fixed ultimately, but I thought I'd toss it out there in case it has not been reported yet. BTW, the animation of the icons flying into their fences is pretty cool. 
Thanks!
