IE seems to ignore elements with higher z-indexes, when they overlap an iframe.
Have read various other posts that suggest adding a combination of &wmode=transparent to the iframe src, and wmode="opaque" attribute to the iframe itself; though IE doesn't seem to like either of these.
<iframe title="YouTube video player" class="media-youtube-html5" type="text/html" width="500" height="300" src="http://www.youtube.com/v/9W82sMSMJJg?hd=1&wmode=transparent" wmode="opaque" frameborder="0"></iframe>
Any help would be much appreciated.
