Hover Pop-Up question

[imported_dfmafia]

I'm trying to get a pop-up just like the username one used in the postbit template.

I have been unable to get it to work all the time and on ie.

      <div class="col4">
           <h3>OPTIONS</h3>
<div class="popupmenu memberaction<vb:if condition="$page_class"> {vb:raw page_class}</vb:if>">
    <a><strong>Hover for OPTION</strong></a>
    <ul class="popupbody popuphover memberaction_body">
<li class="left">
<p>
<div id="footer" class="shade footer">
YOURCODE  
</div>
</li></ul>
</div>
</p>
</div>

this doesnt open all the time in firefox and doesnt even display correctly in ie.

what am i missing here?
