Problem on Windows 8.1 with fullscreen Desktop app

Hello all,

I have installed MonoGame 3.2 (Windows-Installer) on Windows 8.1 (with spring update).
I’m working with VS 2013 Express.

And now my problem:
I created a Desktop Windows app (not Metro) and want to set the
fullscreen modus or switch to the fullscreen modus at runtime.
This is not working on Windows 8.1 but it works on Windows 7.
I have created a OpenGL and a DirectX project, but not difference,
with:
graphic.isFullcreen = true
graphic.ApplyChanges();

Is this a known problem?

Thanks for your answers in advance.

Greetings

Andy
