Hi, I've a problem in showing image in product combination. I've a multilanguage store (en and it) and if I choose a product combination different than default, the image in the left box doesn't update. In Italian languange there is no problem. You can see an example at this url: http://www.sulpiziotartufi.it/teststore/en/preserved-truffles/1332-whole-black-summer-truffles.html Tried in 1.6.0.6 and 1.6.0.8 Any hint? thank you Angelo
