Problems viewing the site with IE7 RC1

There are a number of serious layout problems with the page
http://www.w3.org/WAI evident in Internet Explorer 7 (tested using IE6 RC1
build 5700.6 under WinXP) which mean that content is partially or completely
invisible.

Viewed in IE7, we "see"

i) some image or text partially visible off-left at the top left hand corner
of the window, alongside the blue [Web Accessibility initiative] logo.

ii) immediately below the lower light-blue box which contains links to "WAI
site map" | "Help with WAI site" etc, I see either only the word "Web" or
"aspect", depending on the width of the browser window (tested at 1024x768,
window maximised, then shrunk to approx 75% width). It appears that some
extended piece of text may possibly be positioned under the box so that
almost all of it is invisible.

This problem may of course represent a layout bug in IE7, in which case it
should be reported to Microsoft (at the IE7 bug-reporting site
connect.microsoft.com), or if not, then it is presumably due to the misuse
of CSS hacks.

Best,
