While reading 510570 I found that my custom style for the .pmsig CSS class is being applied to the whole thread, starting from the first pmsig div tag. I looked at the code and found this:
<div class="pmsig"><div class="pmsig-347753"> <font size="-2"> =oQDlNWYsBHI5JXZ2VGIulGIlJXYgQkUPxEIlhGdgY2bgMXZ5VGIlhGV </font> </p><p>
and the divs are never closed. From what I understand, those div tags should be added (and closed) automatically... does anyone know what's going on? I've looked at other recent threads and all the signature divs are closed properly.
