@richard75 – I’m glad you’re enjoying YARPP! Hmm… this isn’t a YARPP issue per se, but one with your CSS. I would recommend you check out quirksmode.org or http://dean.edwards.name/IE7/ to try to resolve your coding issues, using CSS declarations on #relatedposts.
As a side note, though, I love the old Japanese stamps… very very cool. 🙂
