<div tags modified to <p thereby messing up layout

[GilbertZ]

To duplicate this issue, go to Flickr (you need an account to test this). Go to a picture. Blog a picture to your blog (you need to configure your blog in your "Account" page). It posts perfectly. Then "edit" the page. The viewer automatically messes up your layout. After much digging I figured out it was <div turning into <p along with some other code changes.

The easiest way to see exactly what changes is looking at the post in the database before editing the post, then edit the post and save changes, then look at the entry in the database again.

Thank you.
