I took a look at your support ticket and you have a Samsung 914v monitor which has a maximum resolution of 1280 x 1024.
The minimum resolution for Studio One 3 is Monitor with 1366 x 768 resolution, (high-dpi monitor recommended)
The Samsung 914v 17" monitor is not able to run Studio One 3 correctly. This is one of the problems that you are running into with running a monitor that does not meet specifications.
Please update your monitor to a newer model that can handle 1366 x 768 resolution.

As a workaround, you can adjust your resolution to 1024 X 768 to be able to view the box and export audio. This resolution will not work with all windows in S1, so this is just a temporary workaround until you can get a new monitor.
