I'm currently redesigning a website and have run into an issue with horizontal scrolling when the page is viewed in a narrow browser window.
The header contains a logo, some text and a navigation bar and spans 100% of the page width, but the header content is centered with a fixed width of 940px. When shown properly, it looks like this:
However, if the browser window is resized to be narrower than the fixed width a horizontal scrollbar appears (as expected), but scrolling it 'cuts' the scrolled part out, producing the following result:
The work-in-progress site can be viewed live here, if the CSS/HTML can give you any hints as to what I'm doing wrong.
