We have 7 computers running XP SP3 and IE8. 5 of them will display word verification (i.e. Captcha) images perfectly very time. Two will not show them at all, on a wide variety of sites that require them (nytimes.com, toktumi.com, etc.). The two that don't have the same "Medium-High" security settings and 'Medium' privacy setting in IE8. The Captcha box and instructions don't even display, so I wonder about something related to script execution, but that's just an uneducated guess. Thanks in advance for any guidance.
