Hello , A few of my students are having trouble adding sound to their scenarios. Could someone please tell me why this might be happening (see linked screenshot)? https://mail.google.com/mail/u/0/?ui=2&ik=55f558eb15&view=att&th=15fa2e651e9ebdcb&attid=0.1&disp=safe&realattid=f_j9t1n9u40&zw Please look at the pictured link. When my students go to add sound when they initialize the world using this code: Greenfoot.playSound("bellDing.mp3"); A window pops up that looks like the above picture (link) and they cannot do anything else. Green foot won't let them close the window or the program and they are stuck. I checked that their sound is saved in the right place, and that they typed the code in correctly. It is as if green foot doesn't access the file and I don't know why. I know the students have the link saved in the right folder and They are typing it in correctly because for other students (who did the same procedure) it works just fine. This is only happening to a few of my students. I hope someone can help me figure this out, thanks.
