I had Spaces disabled because I didnt use it in Snow Leopard. Now I want to try out the Spaces features of Mission Control but dont seem to be able to. I think its because of the setting I used under Snow Leopard. Is there a terminal command that will let me enable Spaces in Lion, now that the Exposé and Spaces preference pane is gone? Or am I missing something? I drag the iTunes window, for example, to the right side of the Dashboard and Desktop space but no new space appears, and no + is appearing on the top-right of Mission Control at all.
