Question

Here is a jsfiddle http://jsfiddle.net/JcBAd/839/ which demos the problem if you mover your mouse up from the bottom of the list you will see what I’m talking about.

I figure I need to be mores specific with, and not use $(this) or stop other events from firing while the animation is in splaying.

Try this and see if it works for you:

$(".proj").hover(function() {
    $(this).children(".desc").slideToggle("fast");
},function(){
  $(this).children(".desc").hide();
});
