Those MVO Panels are added when a library part of the Library Global Settings subtype is part of the loaded libraries. You can use the Open Object by Subtype… command to see which ones are loaded: in the dialog box look at General GDL Object > Documentation Element > Drawing Symbol > Library Global Settings. You can then remove the one that is creating the panel from your loaded libraries. But the library part will still have code that reads the MVO Settings, so I don’t know if you will need to modify the code of the Basin Built-In 02 so it plays nice with the AC20 MVO Settings.
