I'm using Toad for SQL Server, 220.127.116.11, to create a database diagram. If the table diagrams only contain the field name, everything's OK. If I add the datatype and nullable columns, the columns don't resize automatically. I can resize the column widths, but when I save, close, and open the diagram, the widths for the columns and for the tables are not saved.
we have reproduce your issue, thanks for your feedback.
we have create defectID TSS-1652 for this.
