Short description of error
I'm following the instructions on this video https://www.youtube.com/watch?v=JoW1XWi4Lw0 when I get to 5:33 where I build the crease. Blender lets me build it but when I move the leaf around to take a look at it blender exits. I'm not using a mouse just the buttons on the laptop.
