We're experiencing some comment trouble in IE. We've fixed it, but the problem will persist for a little while unless you clear your cache yourself. To do this, simply go to the URL up top in your browser window and add this to the end:
so it looks like this "//www.apartmenttherapy.com?bustcache=1"
Then refresh and it will clear itself. Or simply add "?bustcache=1" to any AT URL, refresh and it will enable comments again. Sorry for the problems!
