You can easily change the size of the EXACT Orasphere viewer screen; click the button in the top right-hand corner to restore the screen to full-screen size.
To return the screen to a smaller size, click the button. You can then resize the viewer as follows:
If the the viewer screen is not maximised to full-screen size (i.e., the button is displayed), you can move it to any position on the screen.
QUICKTIPS:
If you use two monitors connected to your computer, you can use the mouse to drag the viewer to the monitor you prefer to use for the movies, make it the size you want, and the next time you use the viewer it will play on that same monitor.
Each time you use EXACT Orasphere, it will 'remember' the settings from the previous time you used it, and open the movie viewer at the same size, in the same place on the screen, and with the same sound settings.
