3sixty, it might be good to document your IE6 journey and perhaps we can get your CSS included in core.

Suggestion for you, use the * html CSS hack to target IE6 specifically, then you wouldn’t need to use expressions, which isn’t valid CSS.

So your above code would look something like:

* html .post img {width:400px;}

If I have some time, I’ll look at creating an IE6 CSS patch.
