This is for people using TV-out video cards or dual monitor setups.
Anyways If I run vlc media player and move the video to my second screen it works fine even when full screened.
AES works fine on my second screen as long as it isnt maximized once that happens then @es will show the loading screen on my tv but the actuall full sceen video will go on my monitor.
might not even be a bug in @es as im no developer but incase I wanted to report it
