answer:mediamelon scrolls the worst for me, pawbook scrolls fine. As for websites that scroll badly in generation, it’s the ones with backgrounds that remain in the window, rather than an image that scrolls with the entire page. for example, the background here on ask-public, you see at the top that nice gradient picture, it doesn’t follow the screen as you scroll down, it’s stuck there at the top of the page. The pages you bring up have pictures that stay directly in the window the whole time, and for some reason those are the hardest on browsers. As for between the browsers why one is better, just has to do with its internal programing.
