Please take a look at http://ropeysoles-espadrilles.com/shop/womens-stripey-espadrilles/ where I'm testing layouts. Feature image zooms fine in FF, but IE (latest level) behaves as follows:
- if mouse approaches from below, passing through the area with the thumbnail gallery, zoom works.
- if mouse approaches from the left, passing straight onto the feature image, no zoom. And click produces a fixed enlarged image.
