When I try to compare two images in the Library mode of LR 5, the image on the right - even when it's a duplicate copy of the original image - looks more magenta. I tried using a different monitor - same issue. I tried using LR 4 - no issue.
I'm on a PC with Windows 7 and a NEC monitor. I'm updated my version of LR 5 to the most current.
It's driving me crazy and makes the compare function useless if I can't accurately compare skin tones/color balance.
