Yes, that I know. But once I put in the correct combination, ESC did no longer work. I guess because of the text box?

Hmmm... well You could've found a bug;) But the keys are crappy in this game currently. If You see a test box You have to press SPACE to close it, to exit screens You have to press ESC most of the time. So after solving puzzle: SPACE then ESC. Sorry:P
If its not this, and You want/have time You can write exact steps, because its probably a bug if this doesn't work.
