Yes, thanks.

So, this makes me wonder how IE7 (in standards mode) handles a case like this:

.fullbox { 
	border:.5em solid orange; 
	top:0; bottom:0; left:0; right:0;

It seems like Webkit, Opera, IE8, and Firefox are all doing what they are so that they can draw such a box as a single rectangle. Does IE7 divide it in half, instead of keeping the positioned item whole? That doesn't seem correct either to me, but maybe it is?
