      <br/>
      <p><strong>Bug #1</strong> - after sliding using the mouse, keyboard navigation might not working correctly (fix: set keyboardControl to false).</p>
      <p><strong>Bug #2</strong> - when navigating <strong>and</strong> zooming in the larger image gallery, the keyboard navigation doesn't work correctly with the smaller sliders (fix: set keyboardControl to false).</p>
      <p><strong>Bug #3</strong> - when setting loop to true, inside the swiper options, the swiper.params.control won't be able to synchronize with the other swipers.</p>
      <p><strong>Bug #4</strong> - Not <strong>fully</strong> supported in IE.</p>
      <p><strong>Bug #5</strong> - When you click on a bullet pagination twice in a short time, the slider will freeze and needs a swipe before it works normal again (fix: set clickablePagination to false).</p>
