Distinguish MOVE_UNUSED from MOVE_NO_EFFECT in Galaxies The boundary between them for mouse clicks probably wants to be revisited because at the moment it's slightly inside the edge of the grid. I tried using INUI() instead of INGRID() but that just gives a different wrong answer, so I may need to actually understand what's going on here.
