light mix freez

[baraa usama]

Hello,
whenever i try to adjust any number of any element in the light mix or even when i try to name the photo for saving it the text freezes and the whole light mix freezes... it continues to render normally but it doesnt allow me to write any number in the light mix or even close the render
