Scenario: Cubase 8.5 on Mac all up to date (well not Capitan), creating a workspace with project on the right monitor (Apple Cinema display) and mixer to the left (LG 24 " monitor).
Saving the workspace as global, closing the mixer window on the LG screen, recall the workspace and mixer window now opens BEHIND the project window on the right screen!
Can anyone confirm that this is a bug still in 8.5?
