Hi look at this graphic in Chrome:
http://ing.dk/infografik/saadan-kommer-costa-concordia-paa-hoejkant-16 1737
When you click forward in the graphic, suddenly the sequense appears in the front of the image (wich is at transparent PNG) instead of behind (in the masked area).
This is not a problem i IE or Firefox
What could be the problem. I work with Edge CC
