<p dir="auto">Browser Info:<br>
Using IE9 on Windows 7 SP1.</p>
<p dir="auto">Bootstrap version:<br>
3.0.0</p>
<p dir="auto">Steps to reproduce:<br>
Visit <a href="http://getbootstrap.com/examples/theme/" rel="nofollow">http://getbootstrap.com/examples/theme/</a> using IE9 and click the dropdown link in either navbar example. The drop shadow should appear, but none of the content. All of the elements below are visible.</p>
<p dir="auto">Temp Fix:<br>
Commenting out the <code class="notranslate">#gradient &gt; .vertical</code> line in theme.less for navbars solves the issue.</p>
