Test page still works with current IE8 without the ms prefix. I’m starting to think I don’t need it at all. I had just gone back to “fix” a bunch of pages but they work in IE8 without any extra -ms declarations.

Thanks for the correction, Paul. Indeed it does appear that this syntax is 'by-design', as Microsoft released a whitepaper a month or so after my post which details the change. Whitepaper

Hi James , the test case is incorrect and you have omitted to include the quotes around the -ms filter property. If the quotes are included then it works fine in RC1.

filter:Alpha(Opacity=40);
-ms-filter: “Alpha(Opacity=40)”;

Whether this is by design or not remains to be seen
