Issue
Deleting a Group from the System Plug-in
Environment
TAC Vista System Plugin
Cause
After adding a controller to the Vista database, the System Plug-in automatically creates a new Group
Resolution
If you move the new controller to a different Group, make sure the controller you added is not still selected when you try to delete the old group. By default, both the controller you moved and the group you moved it from will be selected. Hitting the delete key will delete both.
