For those readers who use Internet Explorer 7 on Windows XP SP2, and experience problems on some websites, you might want to try the regkeys found on the following website: http://fiddlertool.com/useragent.aspx
(at least it helped me a lot.) you can check wether you have a problem by visiting www.ford.co.uk. where before the regkeys the webpage loaded several layers in different tabs. now it loads in one tab and thus is readable.
