title: Windows 8 IE11 bug scroll with div in position fixed
body: <p>I have a problem with my new website. I have a div used as a "button to the top of the page".</p>
  
  <p>When i scroll down with the wheel mouse, the div appears BUT changes its position to the right (and a scrollbar appears). I have this problem only with ie 11...</p>
  
  <p>Weird... or not, idon't know, I have been searching a few days now and i have found nothing.</p>
  
  <p>My css:</p>
  
  <pre><code>    #btn_up
  {
  display: block;
  width: 100px;
  height: 100px;
  background-image: url(../img/pagetop.svg); background-repeat: no-repeat;
  position: fixed;
  bottom: 15px;
  right: 25px;
  z-index: 1000;
  cursor: pointer;
  display:none;
  }
  </code></pre>
  
  <p>And my javascript:</p>
  
  <pre><code>$(document).ready(function(){
  
      $(window).scroll(function(){
          if ($(this).scrollTop() &gt; 100) {
              $('#btn_up').fadeIn();
          } else {
              $('#btn_up').fadeOut();
          }
      });
  
      $('#btn_up').click(function(){
          $('html, body').animate({scrollTop : 0},800);
          return false;
      });
  });
  </code></pre>
  
  <p>What do i miss???</p>
