title: Issues with a fixed header sometimes disappearing on iOS
body: <p>I'm working on <a href="http://dev.inprint.com.au/wordpress3" rel="nofollow">this site</a> and am having some issues with a fixed header. Currently, when the viewport goes under 952px width the nav is moved to a bar at the top of the screen with position: fixed. Obviously this is to give mobile devices etc more screen space for content. </p>
  
  <p>The issue is that on iOS7 (tested on iPhone and iPad), when using the dropdown nav to go to a new page, the nav disappears after the page loads and doesn't reappear until the user either scrolls down or changes device orientation. The issue doesn't come up on any web browser I've tested. I don't have any Android or other devices on hand at the moment to test on there. </p>
  
  <p>I've tried looking online for an an answer or even a clue as to what's happening with no luck so far. Anyone have any idea what might be happening and (even better!) how to fix it?</p>
