I'm trying to handle my usb controller (xbox model) via GLFW. I can get it's input, but I see a strange behaviour in my sample application that I couldn't explain. Can you enlight me please? If I disable automatic event polling on buffer swapping (line "A"), the screen content is refreshed but OS part is unresposive: I can't resize, move, etc. With automatic event polling enabled, everything is fine. I tried disabling automatic event polling and calling "waitEvents" (line "B") before refreshing the screen. But, changes to the joystick input do not generate any event, so I need to move the mouse or type a key to release "waitEvents" call. What am I missing? I'm using Windows 7 64-bit.
