Priority on multiple classes about ie7-js HOT 4 CLOSED

If you change the order of your css, then your page will work in IE6:
chnage:
.test.test2{background:#ccc;}
.test2 {background:none;}

into:
.test2 {background:none;}
.test.test2{background:#ccc;}

This is related to CSS specificity. IE7 replaces unknown selectors with an IE7 
class
so that:

.test.test2 --> .ie7_class0

The trouble is that this changes the specificity of the rule. IE7 attempts to 
keep as
much of the rule's specificity as it can. I've improved the algorithm slightly 
in the
next release and this particular bug will be fixed by the change, However, there
where still be occasional situations where this bug will still show up.

This is now as fixed as is possible but still not 100% fixed. :-(
