title: Cannot type in textfields in IE11
body: <p>In my site, I cannot type in textboxes on IE11 on Windows 7. Clicking the text input field, I can see the caret blinking outside the field, positioned in another place in the page.
  I can reproduce the problem across many computers with IE11.</p>
  
  <p>Setting IE8 via Inspector solves the problem, with IE >= 9 it shows the problem.
  The site uses Twitter Bootstrap.
  I tried z-index fixes without success.</p>
