When i drag a Scene into PGV, it does not appear. But when i restart PGV, the new Scene is there. So maybe the Database will not be refreshed after adding a Scene? I tried the Admin-Mode and without it. Both the same Problem.
EDIT:
I tried it with a new fresh Database and it worked. I think there is a Problem with the imported v3 Database.
