System bell beeps on keyboard input in RenderFrames with Panda

[mike]

It seems like if the input is directed to the Panda render window, the system bell beeps on all keyboard input. Directing the input to the wx window stops this and can be done with this code:

        if "win" in sys.platform:
            from ctypes import windll
            pandaWindow = windll.user32.GetWindow(self.window.GetHandle(), 0)
            windll.user32.SetFocus(pandaWindow)

However, as soon as the render window is clicked, it gains focus again and starts beeping.
