Here's an example of some code I put into the product description that gets modified automatically:
<a href="#" class="hearmorelink" onclick="window.open('/Tactiles-audio.html', 'Voice Over', 'width=320,height=1,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,copyhistory=no,resizable=no');return false;">
<div>Want to hear more?<span>CLICK HERE</span></div>
</a>
and it turns it into this:
<div>Want to hear more?<span>CLICK HERE</span></div>
The href tag is deleted completely and it's annoying!
