Do not install or upgrade to gnome-panel-2.22.2-3.fc9.i386

[Kam Leo]

If you have not done so do not install or update gnome-panel. On my
system after updating to gnome-panel-2.22.2-3.fc9.i386 mouse clicks on
the task bar no longer work the same as they did with the previous
version. Left-clicking on Applications, Places, or System does not
cause a drop-down menu to appear. Left-clicking on the Firefox icon
does not launch the browser. Fortunately, gnome-panel-2.22.1.2.6-fc9
is still available on the updates repository. Reverting back to the
older version restored the mouse actions back to their original
behavior.
