I just bought my first iMac last weekend and I love it! My 2 1/2 year old daughter apparently loves it too because tonight while I was making dinner she decided to help herself to it. After I discovered what she was doing, I realized she had somehow changed the coloring on my screen and everything now looks like it is a solarized color photograph. Everything that should be white is black, blue is now orange and so on. How in the world do I fix this? I have no idea what she did. I am a complete Mac newbie so please make any instructions step by step. Please help, I love this computer but now I can't stand to look at it!
