No window control when I open "customize"

Hello All

I have installed the development version of scribes on Fedora 15. The version is Scribes version 0.4-dev-build1023. Everything works fine but when I open the "Customize scribes button", the panel opens and the is no "close" option and there is no window control for the panel that opens. By that I mean the little "X" that is in the upper right corner. Once this panel is open, I can't close scribes at all and I have to kill the process.

Does this have something to do with gnome 3, which is the desktop for F15?

Thanks
