The new Screen Sharing functionality in Lion allows two users to login to the same Mac (one locally and one remotely) and see different desktops.
I have a Mac Mini connected straight to my TV and run Boxee on it. With the new screen sharing, I can remotely log in to the Mac Mini and administer it with full control (using one user account) while Boxee continues to display in all its glory on the TV in the local user account.
However, when I try this, Boxee freezes. Boxee is running on local user account called "Boxee", but when I remote in from my laptop using a different account, that works fine but the Boxee app freezes and stops responding.
If I quit out of the remote sharing and fiddle around for a bit on the Mac, Boxee seems to come back to life.
Further investigation is required on this and I just wonder if anyone else could give this a try and see if they have the same problem?
