Screen doesn't change color
I have f.lux on two Dell Optiplex computers. It works fine on one(Optiplex 960) of them, but when I recently installed it on the other(Optiplex 9010) although I can see that f.lux is working and transitioning colors at the correct time...the screen colors don't change.
I'm not blaming f.lux for this, but I wonder if anyone has troubleshooted this kind of problem and could give me some ideas of where to look for a solution.
I tried the later version, then uninstalled it and went back to an earlier version...but the problem is the same...there is no change in the screen color when f.lux makes the change.
