Argh. On a touchpad computer, sometimes while trying to enter the answer I accidentally click "check answer" while the box is still empty. It records as wrong and sets my progress back, even though I didn't enter anything yet! Could the system be changed so that "check answer" on a blank box doesn't do anything at all? Thank you for considering this.
