stop() on a fading element don't work

stop() on a fading element don't work

Hello,

I can't manage to stop an animation with stop() function.

Here's the code:

$('#test').mouseenter(function(){
    $('#test .navigation').stop().fadeTo('normal',1);
  });

  $('#test').mouseleave(function(){
    $('#test .navigation').stop().fadeTo('normal',0);
  });

I don't know what's the problem, perhaps I'm not understanding stop().

Thanks in advance.
