New metacity buttons don't work properly:
- shade: It works when clicked, but it remains the "shade" button, instead of becoming the "unshade" one.
- stick: It works when clicked, but it then disapears and is not replaced by the "unstick" button.
- above: It works when clicked, but it then disapears and is not replaced by the "unabove" button.

See my Metacity theme:

Enable extra buttons in Metacity general preferences in GConf.

I'm using Gnome on Mandriva 2008.0.
