With adobe reader 8.1.x for linux, you can visualize side-by-side pages in full screen mode. With reader 9.1.2, you can't. When you click on "side-by-side page" button, then "full screen" button, the program returns to "single page" visualization. It 's annoying because I can't take advantage of my 32“ 16:9 monitor/tv. Is there any hide configuration to enable Side-by-side pages on full screen mode?
