It's not that big a deal but it's annoying and I would have thought it's quite easy to fix. When trading technology, on my screen when I select the technology I want from the AI, the box to adjust the amount covers the trade details. In other words I can't see how much the AI values that trade. Worse, it doesn't seem to be possible to remove or adjust the amount of technology which you've added to the trade list; you have to exit the trade screen and go back in. So I have to select the technology and then add one at a time until the text changes to show that the AI is happy with that trade, which seems unnecesarily painful.
