Sorry if the title doesn't make sense, but that's the best I could do. I was trying to talk a screen shot and I think I pressed the buttons funny, when I noticed that instead of my icons being in the random order at any point in the screen, they had suddenly been locked into a line under my HD icon. I can't move any of the icons, what's happened? How do I fix this? I liked having my icons wherever I wanted them, why can't I do it now? Any help (that actually helps, of course) is much appreciated.
