MooTools breaks on IE 9 Platform

Reported by Thiago Lagden | September 22nd, 2010 @ 10:49 PM

I'm using mootools 1.2.4 and I tried out the Platform Preview 4 of Internet Explorer 9 and got a javascript exception, which broke my whole website:

SCRIPT5022: Exception thrown and not caught mootools-core.js

I posted a bug report to Microsoft about this ( and they got back to me.

They say that IE9 doesn't work with Mootools by design because Mootools uses a browser sniffing technique that isn't standards compliant. The IE9 team will not change this behaviour before the final release and it is, in their view, the responsibility of the Mootools developers to fix the library.

I hope the developers do this, because if they don't, I'll have to migrate one of my websites to another library.
