Question: In world of warcraft when you use the pixel zoom on some of our tools to pick a color when calibrating and move your mouse over something, the center color picker is always gray, not the color you are holding your mouse cursor over. Changing the resolution will not help and it will not pick the correct color.

Answer: In WOW in your settings there is an option to use "Hardware Cursor". Try checking this and see if it corrects your problem
