We're having a problem with the website http://ttdtestbed.com/crs/.
The sticky post images that display on the front page don't render on IE8, leaving a big, gaping white hole. See a screengrab here comparing IE8 with Chrome.
I've searched at length on the forums and while I've found similar problems, there's been no definitive fix.
I'm using a child theme for all my edits.
