Layout problem with index.php?action=unread

[olioli]

Hello.

Congratulations for the gold version 2.0.
I have just made an upgrade from 2RC4.
Everything goes well.

Except this: look at the capture of my screen and compare with that of the same page on simplemachines.org
Can anybody help me or give me guidlines? css? recent.template.php?

The problem can be noticed here : hxxp:gallika.net/smf/index.php?action=unread [nonactive]

Thank you very very much for your answers.
