Drop down menu is Glitchy at the edge of menu button

I have an odd issue. I created a standard dropdown menu but I am having an issue where the menu is dissapearing when I get right between the menu and the drop down. I cant find any css that would stop the hover state but maybe your eyes are better than mine.

Here is a gif of what is happening: http://ift.tt/1IxqoZM

Here is a link the current version of the website: http://ift.tt/1CnImXz

My js code:

//------- NAV MENU --------//
$('nav li').hover(
  function () {
    $('ul', this).stop(true,true).fadeIn({ duration: 300, queue: false }).slideDown(300);
  },
  function () {
    $('ul', this).stop(true,true).fadeOut({ duration: 300, queue: false }).slideUp(300);
});

Relevant HTML:

<nav>
  <ul class="center">
    <li class="menu">
      <a href="#Home">Home</a>
    </li>
    <li class="menu">
      <a class="inactive">Get Started</a>
      <ul class="dropdown hidden" id="drop1">
        <li class="dropitem"><a href="#Start">Start Making Your CCR</a></li>
        <li class="dropitem"><a href="#HowItWorks">How CCR Writer Works</a></li>
        <li class="dropitem"><a href="#Why">Why Choose CCR Writer</a></li>
        <li class="dropitem"><a href="#MyPrevious">Access My Previous CCRs</a></li>
      </ul>
    </li>
  </ul>
</nav>
