Programs that lock the computer : <p>At my school we have started using a new typing software for our exams. This software is called Digiexam: <a href="https://www.digiexam.se/en/" rel="nofollow">https://www.digiexam.se/en/</a> When Digiexam is started the computer freezes so that the program window won't be shut down until the essay is handed in. As I have understood most of the code is written in css and javascript. To my question: How can you freeze the computer like this using code? </p>
