hi, suddenly this morning my mbp 17 unibody has horizontal lines when reading this page. btw i'm using safari beta 4. is it a bug in safari 4 beta? or the graphic card issue? it doesn't happen in other pages though. has anybody experienced this? it's like i'm getting stoned while reading that article about smokin pot. i quit safari and then read other pages include that one again, those horizontal lines dissapear. tell me it's not the graphic card issue please... hope it will not show up again. the url that has horizontal lines is http://digg.com/d1npDT can you guys check that page out and tell me whether you have the lines or not. thanks..
