they do present some pretty serious problems. First off, the font: There's a general rule that if you use a specialised font in your logo that you shouldn't use it *anywhere* else. Otherwise the logo disappears.

Another thing that makes a logo disappear is pushing it into the background, and unfortunately that's exactly what the rounded and bevelled boxes for navigation, etc. do. Seriously take a good long look at the page in three dimensions and see if you see the same thing happening.

If anything the navigation should *recede* slightly as so to push the content up front.

Anyhow, fly this post past your the IB designer and see what s/he thinks.. :)
