I never understand why people have to behave like this... Clearly one needs to wind the shutter for the white dot to be in place for the meter to read accurately. Leica decided, quite smartly I might add, to disable the meter when the camera wasn't cocked, so people wouldn't try to use it like this and get erroneous readings if the camera attempted to meter off the black curtain. So the white dot on the curtain metering system is EXACTLY why the meter was designed not to operate until the shutter was cocked. Next time, try to be a little bit less rude if that is possible for you.
