yeah i dont like how the trade system dialogs are set up, i think they should have more specifics, like the export/import, what you are paying, what you are getting, and when it expires.
also, i seem to have problems cancelling deals myself. once i trade a luxury for some gold and a tech, but after 20 turns i could not cancel the deal - the book said something about right-lcicking the export, but that only brings up the 'pedia. what am i missing?
