Locking my computer exits the game.

Please fix this. I live with a real ass hat of a brother so when ever I have to do something small or big I lock my computer. I've made it muscle memory at this point because my brother will change my steam profile picture to "Tyler the Hedgehog".... Don't search it up, seriously. Of coarse i'm not a big enough prick to do these sort of things to him so there isn't really a way around this. Please, please, please fix this annoying bug.

 

GM:S port has probably fixed this.
