title: jQuery UI Show/Hide behave different than jQuery show/hide? Maybe a bug?
body: <p>What I’m trying to do, is a simple toolbar that shows/Hide when I mouseover/mouseleave over to parent.
  It’s a little bit hard and long to explain, so I did a sample of the problem here:</p>
  
  <p><a href="http://jsfiddle.net/Ppr4N/44/" rel="nofollow">http://jsfiddle.net/Ppr4N/44/</a></p>
  
  <p>The box on the top works the way I want. I use .show(300) and .hide(300) I think this are the regular methods from jQuery.</p>
  
  <p>On the bottom box, I use .show(“slide”) and .hide(“slide”), I think this methods are extended by the UI.
  The problem is that when I move the mouse over the “Bump”, the toolbox hides and shows like a maniac.</p>
  
  <p>By the Way! I'm using UI 1.8.10 and jQuery 1.5.1, (both from MS CND) I also tried with a couple of old versions and the result is the same.</p>
  
  <p>Any Idea why this is happening?</p>
  
  <p>Thanks!</p>
