Looks like the right side is cut off. The links Apple, Microsoft, Security and More isn't showing to the right of IT. Drivers, Extra and the About tabs are missing too. No search box either.
I see something similar when viewing in portrait on my Asus TF700T, using the build in, Firefox and Chrome browsers. The Drivers and Extra tabs are gone, no Search box. Features and Reviews, Trending Tech Products, Hot PC Games Releases, etc. aren't showing either. But the web sites is back to normal when the tablet is in landscape mode.
Haven't noticed this until now, since the tablet usually is in landscape.
