Also, this bug disappears when I use the free InputMapper program that allows my controller to map to XInput for steam game usage, so it must be a controller mapping issue rather than my code. Does anyone know what may be causing this?

Hi, I'm building a client/server for game controllers using SDL2's new Game Controller API. Everything is working excellently...except for when I poll an SDL_Event, the right trigger is polling as both the cbutton.button (SDL_CONTROLLER_BUTTON_LEFTSTICK) and it's normal caxis.axis (SDL_CONTROLLER_AXIS_TRIGGERRIGHT). I checked my code to make sure I didn't miss any break statements between the switches as well as my values on the server side. The debugger stops on SDL_CONTROLLER_BUTTON_LEFTSTICK(this happens after It already stops on it's proper caxis.axis event) when I press the right trigger. Any insight as to why this might be happening would be greatly appreciated, especially from the library developers Thank you! My computer is a Del Inspiron 15 7000 series with Windows 8.1 and i7 Processor. The controller I'm using is a Playstation 4 controller. Here's the code: Code: void InputHandler::HandleInput(bool & quit) { while (SDL_PollEvent(&inputEvent)) { switch (inputEvent.type) { case SDL_QUIT: quit = true; SDL_Quit(); break; case SDL_CONTROLLERDEVICEADDED: cserv.AddController(inputEvent.cdevice.which);
