Example is posted in a moderator thread in the moderator planning forum. PM for link.
The symptom of the problem is that the link to the attachment does not work. Hovering over the attachment link in the post does not enable the hand icon to enable clicking on the link.
The source for the post looks like this
<div class="attachment xls">
<span class="itext type_xls"><strong><a style="cursor: default">file_name.xls</a></strong><span class="details">39424k .xls file</span></span></div>
