I just noticed something odd... I was bored, so I Spotlighted the keyword "dog" and it came up with a picture called Dog. When I opened the picture, preview opened the file. I then decided to minimize it; but when it went into the dock, a black pixelation (if you will) surrounded it's minimized icon. I thought this might be an Intel thing until I tried it out on my Mac Mini (1.42 GHz G4) and the SAME thing happended! :O Is this some obvious glitch that Apple overlooked? I love Apple, but this is wierd and the first (knock on wood) visual fault I've seen in Tiger. On my Intel MacBook: On my Mac Mini: Any thoughts?
