Web Browser in WP7

I got my Nokia Lumia 2 days ago. On my old Iphone 3gs when I went to yahoo or MSN, I could scroll through the pictures of news stories on top of the page by flicking the pictures. On android, you can click on the next button. On windows phone, it just shows 3 stories. If I switch to the desktop version, there are more stories and it shows 5 pictures at a time, but clicking next goes to the next 5 instead of the next story. Is there a setting I'm missing or these sites coded better for apple and googel than IE?
