Just noticed that when I click on the button to view my preview on an external monitor, it displays a "White" screen. This has not happened before. Before when I click on the button, the preview would play on my Preview Monitor. Now it just shows "White". Any idea what cause this? And how to get it to work again.
Running Movie Studio 17 - Build 143, Windows 10 64bit with 32GB of memory.
Thank you.
