Ok Dfort on the 650D, Tested versión 105 I found at your downloads page and as well as the 100D,
When I turn off the camera in crop mode and turn it on again remains in crop mode,Fantastic Function. Thank you!!
From Canon Quick Menu Can not disable Crop switching to any other resolution it just doesn't move stays fixed in 1080 or which ever resolution is in.
However it does disable crop mode from Canon Standar Menu which is great, Probably you can fix the error on Canon quick Menu.
