I am learning how to make interfaces in the game engine, and I have set up 2 buttons: an exit button and a play button. When one of the buttons receives a left click, it either closes Blender or goes to another screen with a monkey.
The problem is that both buttons are doing the same stuff at the same time. They're switching scenes and closing the program, and the biggest problem is that I don't have to click on the buttons at all. When testing, I can click anywhere in the Blender and it does this.
Here is the .blend file if you need it.
