Yesterday I updated my Surface RT to Windows 8.1 from the Store app.
After that, I did some search using Internet Explorer App. And, I've tap and hold over the results links (so I can open the result in another tab), but, when I went to the new tab, the page seems 'frozen', I cannot scroll down at all.
This behavior is happening randomly (some tabs are 'freeze' while others are working just fine), and I tried Windows 8.1 Preview before in other PC, and saw this bug too. So, the final version of Windows 8.1 doesn't seems to 'fix' this bug still.
