Hi. I was under the impression that we had fixed this bug but I've been able to duplicate the problem so clearly we didn't.
To get around this problem, after making your changes, press F5 to execute the changes against the SQL Server This will automatically save the changes in SQLDBControl. Then close the editor and check in the stored procedure from the summary view. If you check it in from the editor it won't work.
We'll tackle this as a priority and will aim to get a fix for it as soon as we can.
Thanks for bringing this back to our attention.
