"The top left field shows the currently active show. Your editing will only affect this show. If multiple versions of a particular show have been created, you can select one of your alternate versions by clicking on the arrow to the right of the field. NOTE: Sinfonia considers Acts as individual shows. You will only see the various versions of the currently active show (i.e. Act). See 'Loading A New Show' or 'Edit Show List' for instructions on switching acts."
