if you click add trade in, the window pops up. you fill it out. however, sometimes you accidentally click outside of the window, which causes it to close, and delete all the data and the progress. no pop up message exists to ask you if you mean to dismiss the data without saving progress. Also, sometimes you can click. on the boarder, or click something near the border, and because of the imprecision and error, you can inadvertently click out past the border, closing the interface and losing all your data and having to start entering the information all over again.

This seems like a bug because it should ask you before deleting all your data. and the interface should only be closable intuitively by clicking the X. so its unintuitive that if you click somewhere on your screen, the interface closes and you lose all your progress. Just seems like it's not tested.
