Just a FYI that there is a problem using Chrome as the browser with Apsona.
Scenario:
1) load in english.
2) import/insert some new products from a csv. ok.
3) change to secondary language.
4) import/update these products with second language information from same csv. Flags errors as it cannot find the model number, (nor product id if added to the csv prior to the update).

The process works ok with Firefox and IE.
