FCPX 10.4 Balance color's eyedropper doesn't select color
Trying to use Balance Color's eyedropper, select "white balance" in dropdown menu and then select color on image by pipette and click it. But nothing happened, It doesn't select any color - indicate "no color sampled".
Have someone have such problem?
