Hi so I'm having some issues with this. I compile everything (from first post) with no problem and run the program. Everything looks good, borderless windowed mode, I set the fire key to "k", I adjusted the box, and pressed start, but it just doesn't work. Sometimes it will go red and say I may be screenlocked the first time I press start, but it generally goes away if I alt tab back into the game. Also, I checked with lightshot and I am not screenlocked. Thanks for your time!
