Why can't I see the Tobii Pro Studio Live Viewer or Track Status windows?
Sometimes the Tobii Pro Studio Track Status or Live Viewer windows can open off screen, depending on previous dual screen settings.
Open Tobii Pro Studio and go to Tools, then Settings and in the Miscellaneous tab you will find the option to "Forget Live Viewer window position". Click this button, then "OK". After that, restart Tobii Studio.
You can also click on the LiveViewer or Track Status icon on the Windows taskbar, and use the Windows key of your keyboard and the left or right arrows to drag it back to the main screen.
