On some computers running Windows 8 OS the IntoScience Windows App may fail to enter fullscreen mode correctly. This can be fixed by setting the compatibility mode of the IntoScience App to Windows 7 mode.
To set the compatibility mode:
1. Select the IntoScience App and right click to get properties
2. Select the compatibility mode tab
3. Select Windows 7 compatibility mode.
The App should now be able to enter fullscreen correctly.
