Try pressing F11 key if your screen is small (netbook computers). Press F11 again to restore. With Opera, clicking a couple of times on the open window tab at the bottom of the screen may improve things further. The Opera browser works massively better than any other browser with this page (especially when holding down return key to repeat button clicks). Firefox is the next best.
