Cut-outs and weirdness on my web page in Safari...

Hey all, my web designer has been struggling for weeks to solve a problem of cutouts and graphic weirdness on my new website, WHEN viewed in Safari and Firefox.
Here is the site link:
Ministry Downloader.

See the graphic weirdness problems along the right margin especially?

Also, this page is a great illustration of the cut-out problem...

Ministry Downloader Register

Any ideas?

Thanks!
