[/quote] Correct [quote='824996022, DTS Engineer, /thread/774365?answerId=824996022#824996022'] Also, please send attach a screenshot that shows "... while "Objects in Orbit" immersive space was presented alongside with the main application window." to put this into context. [/quote] Here is the screenshot, red arrow points to what I referred to as the main application window and blue arrow points to immersive space content
