Here's a screenshot of Fedora 15 (running on VirtualBox). Please notice that cairo-dock has an "application menu" applet. (Click to embiggen...)
Now, here's a screenshot of Fedora 16 (running on my computer; I just upgraded). Please notice that cairo-dock no longer offers the "application menu" applet.
(it's the same version of cairo-dock: 2.3.0.)
For the love of God, what happened to the application menu in cairo-dock on Fedora 16? It's missing.
