A column named 'Size' already belongs to this table.
Data Dictionary Creator was working fine for me, but now I can't get it to work at all. When I attempt to connect to a database, any database, I get a database connection failed message. When I click on the "Connection Exception Details" link I get a popup with the message "A column named 'Size already belongs to this DataTable". When I click the elipsis button and set up a connection string I can test it, and I get a successful connection message. When I close the screen I'm right back to the connection failed message. Also, I notice on the "Advanced Settings" tab, a whole bunch of field names have been added to the "Document Additional Properites" box. (See attached screen shot.) Uninstalling and reinstalling Data Dictionary Creator did not resolve the issue.
