Credit to the project on the screen (Made by me) I pretty much hate the fullscreen thing now. It's like when you do it, that happens and you can't do anything, meaning you have to quit the tab, make a new one and put Scratch on it! So that means the only way to do that without it going like that is to press See inside, and then fullscreen it. (I don't press See inside because I think I'm going to get accused of breaking the code in the project) I wish Scratch would fix this sooner or later.
