Clicking sticks opens the Vorpx menu

Just got Vorpx and I'm already frustrated, but hopefully someone here knows a solution. I want to play games using my controller, but clicking in the sticks opens up the Vorpx menus. I have not found any way to disable this. I don't want my controller to interact with Vorpx at all, the keyboard is fine for that. Does anyone know where to find this setting?
