We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Inconsistent method signature (or missing hook?)
Windows XP, Psychopy 1.80.06

window.flip calls dispatch_events() for each _eventDispatchers (pyglet winType), but DirectInputDevice (hardware/joystick/pyglet_input/directinput.py) has a different signature for that method: _dispatch_event. Needs to be fixed somewhere.
