Application appearing on all spaces in Lion I had a couple of applications set up to be on all spaces when I was running on Snow Leopard, but now that I'm on Lion I want to turn that off.

I can't work out how to do it. Does anyone know how? There doesn't seem to be an option in System Preferences for it. Perhaps there's a plist or something similar I can edit?
In the dock you can right click the application, go to Options and de-select the option there.
