I just installed the 7D nightly build (2014.Aug20.7D203(1)) successfully. Somehow the scroll wheel is not adjusting the aperture value as assigned in the custom settings menu. I tried changing the function to change the shutter speed. Once changed it did not work there either. The scroll wheel works just fine in everywhere else and I can change the value with the q button. And upon further inspection it does not want to adjust exposure compensation either in Av or Tv modes. I apologize for re-posting this but I forgot to label what component or version this pertains to.
