Hi all,
Working with SQL Server 2008 I have been a curious thing, then I created a table and I forgot to make a field auto-incremental. I've re-opened, I put the Identity = True and going to save I get a message that says "Saving Changes is Not allow" ("save changes not permitted"). It seems to be a security measure and to fix the editor must go to Tools, Options, expand Designers and Designers Database Table and remove the check to Prevent Saving Changes That requires the table to Be re-created check box (in Castilian would go to the Tools menu Options Designer, Table Designer and Database)
