Quad screen configuration with windows xp and a nvs 440, I am running display fusion on top of that but all that does it enable quad screen wallpaper. if I full screen a you tube video on any screen then click off on another screen the you tube video loses full screen. How do you stop this?
You can't, as far as I know. Youtube's code monkeys didn't consider multi-screen users when they wrote their part of the interwebs :/
I dunno if it will work, but a possible workaround would be to put youtube in HTML5 mode, so when you click fullscreen, it just fills your browser, then hit F11 to make your browser full screen.
What i always do (triplescreen user here) is use the button that opens the video in a popup: It's that third button from the right. Not all videos have it unfortunately, but the window it generates is stretchable to fill your screen
