Cannot change the default database reference while designers are open.

You cannot change the default database reference while using the designers to create or modify a query, view, inline function, or stored procedure. This warning occurs in two circumstances:

• You are changing the default database reference for a folder while some of the folder's documents are still open in the Query and View Designer.

• You are changing the default database reference for the entire project while some of the project's documents are still open in Query and View Designer.
