This message occurs, If you are the administrator, when you are attempting to restore backups or restructure databases, and other users are still accessing these databases (remember that the Q++Studio Broker is also a user).
•You will have the option of shutting down the Q++Studio Broker, running on the server, and letting other users close down Q++Studio, before proceeding.
•If you proceed anyways, you will be restricted to restoring backups to your local drive.
Non-administrator users do not get this message, as they are always restricted to restoring local tables (ie. tables on their PC).
