sorry posts seem to have crossed.... will look at the nested div as well but it is defintley one single blog post that is causing the issue.
if i leave it in and add a new blog post, everything goes back to normal... if I then re-create the offending blog post then it goes back to throwing things out...
edit... just looking at the nesting issue and the content div and left column areboth within the contentWrapper div but not nested within each other....
