Youtube fullscreen only fills browser window
When I am watching a video on youtube and I click on the "fullscreen" icon, instead of filling my entire screen, the video only fills the browser window. This has only started happening recently (after I messed with my proxy settings). I have restored the proxy settings, and it hasn't seemed to help - I'm not sure if this would affect youtube, but it was the only thing I have changed recently. Would very much appreciate some help.
