Somehow, I managed to completely massacre my OS. Click and drag (for Icons, text, the dock, pictures.. ANYTHING.. click and drag) does not work... also, icons of programs I download are not showing up.. they are simply Folder icons i think these problems happened after I ran these commands. I am ultimately annoyed as much of what I do is now extremely limited... can anyone whos a bit more UNIX aware help me find out what i've done?? I would very much appreciate any help!!
