Has anyone had this problem before? I get weird streaks of pink going all accross my iBook's screen. But then if I nudge the screen, the pink goes away. Anyone know what is causing this? Is my screen somehow getting twisted/distorted? Or is it something more serious like a loose connection. If anyone has any insight/advice I'd greatly appreciate it. I just don't want this to turn into one of those situations where the screen gets progressively worse until it's unusable...
