OK, experts. A friend of mine wanted to try Linux out so I install Mint in his old BioStar/AMD computer. I was working great when I gave it back to him, but he like to tinker with settings. He now has 3 clear square blocks on the outside of a web page so the web page does not take up the whole screen. See attached picture and see if you can figure out what he did. I'm hoping it's just a setting somewhere and not a fresh install. [file name=Screenshot3.jpg size=86510]http://www.linux.com/media/kunena/attachments/legacy/files/Screenshot3.jpg[/file]
