I don't know if this is a bug, however after upgrade to 1.4.2 the "add to cart" buttons on individual product page have disappeared.
No other parameters have been changed, other than importing language file.
Is this just my problem, or are others affected?

//Another question/request (that probably should be moved to antoher section): Users need a "back"-button to give them a chance to review pages before proceeding to chekout. This should be easy to add?//
