"Microsoft Expression Web 3 SuperPreview for IE"
I happen to have the full version of Expression Web 3 and it does have SuperPreview. I hadn't tried it before. That's a great tool.
Expression Web SuperPreview for Internet Explorer is a standalone, free application with no expiration and no technical support from Microsoft.
I'm sure this will also support IE9 when it's released.
