I don't know if this is related to it still currently being a Release Candidate or whether it's a general bug in Unity, but when I logged into the Unity Desktop this morning I had an error saying no Driver found use the Desktop Edition when logging in. A quick re-boot solved the problem, will let you know if this bug goes away in the final release or whether it's still there in a later post after I have upgraded to the final release on Sunday.
