I have almost a full page scroll of different variations attempting to get something out of a carton. I think this needs to be looked at, because it is wildly unintuitive, and there's no command hints in the 'examine' of the carton.
Literally left a delivery carton laying around for a week one time, baffled as to how to get anything out of it. And that was with four of us going at it.
That's what I remember about dealing with this a long time ago. I don't know whether it's the same as the issue you're experiencing today.
