sIFR problem in IE document.defaultView.getComputedStyle

I have sIFR 3 r436 working perfectly in all browsers except IE.

IE throws 2 errors. The first is: 'document.defaultView.getComputedStyle' is null of not an object This is on the sifr.js file

The second is: 'sIFR' is null or not an object This one is happening I think due to the fact that the sifr.js script is failing in it's load.

Has anyone had anything li开发者_如何学运维ke this before?

Thanks, Jai

Found the problem. The CMS I use, Jojo, minifies every js and css file that it serves. When I finally worked out to test the file by bypassing this it worked straight away.
