Symptom
When copying an existing Millennium group or user, the new group does not show up in groups nor user maintenance.
When you click copy, the system indicates copy is in progress but the copy is not successful.
This is occurring in version 2015.x-2016.1.2 of Millennium but fixed for 2016.1.3 with a new millsys.dll and millsys.pdb file.
Turning on a SQL Profiler Trace results in the following user error: Could not find stored procedure 'sp_addgroup'
