Where is the Score?

I`ve just downloaded and installed MuseScore for the first time ( version 0.9.3. ). I created a new score by giving a title and composer, choosing and adding some instruments, selecting a key signature then time signature and number of measures then after pressing Finish - where is the Score? All I have is the same grey rectangle with the little black box in the left hand corner. Is there something else I should do to see the Score? (I`m using Windows XP, by the way).
