When I go to insert a sprite in SW's Build Editor, in a new board, the editor exits if it is, or as soon as I go into, 3D mode. However, in a loaded map with some sprites already inserted it's fine. I believe the error lies with the first default sprite that gets inserted in a new map, which I haven't seen but has this on it's label in 2D mode: '5:2,'. And that's a weird label from my knowledge! I checked it's low and high tags and they are set to 0. Weird, huh?
