PNG Transparency and Layout issue in IE9

I havent encountered problems like this with IE9 yet. Normally, everything renders just fine. This site: wp.thebookplace.org is loading and rendering fine up until the last second, then the pngs get a red X over them. On other pages, some PNG background images load fine, then at the last second jump out of place. It seems that some file, a stylesheet or something that is being loaded last is causing the problem. Any ideas? Thanks.

I quickly resolved the issue after posting here. For anyone interested, I had multiple IE png fix's that were apperently colliding with one another. Removed one and issue solved.
