Hi Kathy,
I would think the behavior you are seeing is by design. In order to share a database, you need to ensure it is stored within a normal file share and ensure each user basically has full control permissions on that folder.
Based upon the warning message you are seeing, it sounds like you can still make data changes to the database, but you just can’t make design changes. In order to make a design change all you would need to do is make a local copy of the database, make your design changes, and then publish the database back to the site. In any scenario, I would think you would normally want to make your design changes in a copy of the database and then when you are finished testing, move it back to your production environment.
