Recently certain pages will not display or only partly. I noticed this behaviour on IE8 as well – and I cannot get it right.

Examples:

http://www.aarp.org/ no presentation at all

http://www.vitalitools.nl/nl/tfa/30202802_thermometer.php

IN IE8 one can hit F12, opening Development Tools. Under tab DISABLE one can switch OFF/ON CSS, Pop-Up Blocking and SCRIPT.
