Custom Dashboard Refresh Button Not Working

On the custom dashboard in the Self Service Application, the Refresh button does nothing, here is the code (copied from documentation)

<div><font size="1">
     <a href="cid:load?page=_dashboard.html">Refresh</a></font>
</div>

Is there something to do for this button to work properly? I have other relevance working in the dashboard like computer name, uptime, IP, etc.
