Dropdown Menu with 20+ items gets cut off by a views content rotor
This is an awfully localized question, but I got this to work fine in Chrome and Firefox by adding:

position: relative;
z-index: 1;


to the slideshow block (&lt;div id="block-views-speakerslider-block_1"&gt;) or any of its containers (&lt;div id="wrapper"&gt;, &lt;div id="content"&gt;, etc)
