It seems that in windowed mode the resolution is locked at something to the order of 653x367, where I could force it to display in 800x600 and it would just stretch the image, which I _think_ is why input isn't accepted properly in windowed mode. Audiosurf expects the input where the controls would be if the resolution were actually set to what it wants.
