Window goes fullscreen when pressing play

On my Windows 10 machine Audirvana occupies the entire screen. The task bar is visible. So far so good. However, as soon as I click on play the Audirvana window goes full screen for a couple of seconds and then occupies the entire screen (overlaying the task bar as well). After a couple of seconds everything goes back to normal.

Sorry, but I can’t figure out how to check for the Audirvana version on Windows. :wink:
