Any idea why OmniDictionary doesn't appear in the services menu? I'm in a cocoa app, but it doesn't show up. It is in the OSX startup partition in the Applications folder, so it should work, right?
OmniDictionary is now a rather old program, as OS X software goes. I believe it was released before the 10.0 retail version came out. So it wouldn't surprise me if one of the X updates broke it.
