Windows Forum / Internet Explorer / General Topics / June 2008IE7 using IE6 conditional comments - fixable?
Hi, I've noticed today that some sites I've visited, for instance http://www.lightningsource.com , don't render correctly. I've tried no-addons mode without making any difference, and I've tested IE7 on XP SP2 on another machine and it works fine. Running Fiddler I can see that for the site above my IE7 is pulling down the CSS files that are in the IE6 conditional comments, and ignoring the IE7 CSS file - it's parsing the conditional comments as if it's IE6. I've check the user agent string, both manually in the registry and using the User Agent String utility, and it's set correctly to just (default). I've re-registered all the IE7 DLLs, and still no change. Has anyone seen this before? Other than removing IE7 completely from XP SP2 and then reinstalling, is there any way to fix this? I'm not sure how long my IE7 has been doing this, until today I didn't think to try using Fiddler to see if something odd was going on so other sites I've looked at recently that don't render correctly may have been a result of the same issue.

Just wanted to provide some version details and a Fiddler session output showing the issue.

Aha, found the source of the problem - the Version Vector value had been changed by something (or someone ...) to cause it to act like IE6 for some request handling. If anyone else ends up with the same problem, you can fix it by running regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Version Vector and if there is an IE value in there rename it to zIE (renaming allows you to put it back if it breaks something else, rather than deleting it).

Mine is REG_SZ 7.0000 on machines with IE7.

Apparently if it doesn't exist, IE checks the loaded modules to obtain the version data. So far it's been working great with the existing key having been removed, but it should be fine with that value too. I've tested it here: http://www.positioniseverything.net/articles/sidepages/cond_1.html and it correctly shows all the parts that should be for IE7 in blue. I've also tested it with a Version Vector of 7.0000 and it shows the same results. So long as that value always matches the running version then there shouldn't be a problem. I still haven't worked out what might have changed it to 6.0000 . Apparently IE5 for Windows 2000 has a Version Vector value of 5.0002, which makes conditional comments like [if IE lte 5] fail to work as expected, as 5.0002 is not less than or equal to 5.0000. :S SignatureDan |
