It took me all day to try and figure out why recording.org Threads looked goofy all of a sudden. The threads top and bottom where our sponsors ads go had a iframe in them making to OP (top post) and the last post bunch together with the banner ad.

Once I realized I had the IE compatibility view on, I removed this and the site looked perfect again.

See Tools > Compatibility View> uncheck> perfect!

Hope this helps.
