I’ve found this bug a while ago but for some reason, I didn’t report it, when you are in sprite editor you can leave game editor. This can cause the ESC key to leave editor to delay for a long period of time.
@AbstractGallery, This also happened to me.
Yeah, its a bug.
This what happens when you press esc while in the sprite editor. Just press esc again and close it.
It doesn’t break Flowlab and its easy to fix, so this will probably be fixed when the sprite editor update comes around (the update after Data Type update).
Ok, thanks @JR01
