With this set my EPS files are not rendered in ABCpdf, but set to EmulateIE7 and they work fine.
I know EPS aren't a standard web format but they are embedded into a PDF using a bit of ABCpdf magic.
Because IE8 isn't even trying to show them they are not appearing on the PDF as they previously were.
