Warning: Diagram has possibly been modified by another user.

[Bill Egge]

I get the following error every-time I edit something - I am the only user. The project is a brand new SQL Server Database created using the 1220 scripts.

"Warning: Diagram has possibly been modified by another user."

I searched the forum and found 3 threads but no solutions.

I am using SQL Server 2014 (12.0.2254).  The only defaults I changed on the database were Recovery Mode to Simple and Auto Shrink to True.
ODBC Driver is SQL Server Native Client 11.0
Database and ODBC name has an underscore in it, problem?  "EA_EGC"

EA Version 13.0.1307
License is Corporate

I think I found the problem.  So far I am not getting the error.

Solution:

When Opening the project using the wizard, choose "Microsoft OLE DB Provider for SQL Server" and NOT "Microsoft OLE DB Provider for ODBC Drivers"

That is what the help says you need to use anyway.
