clear both is needed on pages with info boxes(branch,..):
<pre>
style.c:
  /* Put the footer at the bottom of the page.
  ** the additional clear/both is needed to extend the content
  ** part to the end of an optional sidebox.
  */
</pre>
This is added INSIDE the conten area. I'll try to move this to the footer style. This will require edits on all existing footers, because this has to be added to the footer style definition in the configured CSS.
