CSS :hover in Internet Explorer, hover-off event

I am using the :hover property from CSS for A links (since IE doesn't support other elements) to create mouse overs for a graphical menu. Firefox and Opera both currently display correctly and Internet Explorer appears to do so as well at first glance.

However, when the mouse is moved quickly, the mouse-out event appears to not trigger. The :hover graphic sticks. The following image demonstrates this:

If anyone has any ideas on solving this problem please let me know. I'm NOT using any Javascript and I did try to make use of display: block;, but that didn't help.

Code


<!-- Background image for each tab. -->
<div class="tabs">

   <!-- Encloses all graphics containing tab text. -->
   <div class="tab_text">

       <!-- Uses an empty pixel as the main image,
       with the background changing on mouse over. -->
       <a href="" class="tab_home">
           <img src="_.gif" class="tab tab_home">
       </a>
   </div>
</div>
