IE 9 in “Quirks mode” is lower in regard to standards compliance than “IE 7 standards” Document Mode. addEventListener() certainly is not available there. One should never rely on that a document only renders correctly when in “Quirks mode”. The light at the end of the tunnel is that there are rumors that Microsoft is going to replace Internet Explorer in favor of a lightweight rewrite codenamed “Spartan”. It remains to be seen if this comes true and if the result will be in any way more pleasing than what we have today: <http://www.zdnet.com/article/microsoft-is-building-a-new-browser-as-part-of-its-windows-10-push/> This fits well with official information that support for IE 8 will be discontinued, and for IE 9 and 10 reduced, starting next year: <http://www.techradar.com/news/internet/web/abandon-ship-microsoft-will-kill-support-for-internet-explorer-8-in-2016-1260907> -- PointedEars FAQ: <http://PointedEars.de/faq> | SVN: <http://PointedEars.de/wsvn/> Twitter: @PointedEars2 | ES Matrix: <http://PointedEars.de/es-matrix> Please do not cc me. / Bitte keine Kopien per E-Mail.
