I'm not sure what is going on, but some time ago my Spotlight icon in the menubar disappeared. Now for some reason the Eject icon is on the far right where Spotlight should be. Also the keyboard shortcut is not working. To do a search I have to now go to the finder and hit Command-F. I really miss not having Spotlight helping me with definitions. Anyone have any idea?
