title: slidedown and slideup looping bug in firefox

  <p>I have a menu exactly like the one on queness, so check out the demo to see the issue. Basically, if you're using firefox and your mouse goes up and off the button vertically you can get the slidedown and slideup to sort of flicker in a loop. Play around and you'll see it's pretty easy to do.</p>
  
  <p>Is there a way to fix this? For some reason it only happens in firefox.</p>
  
  <p>Thanks</p>
