Kirk, actually I think it is not a Windows sync issue. I did some more testing. Created a test folder with an image on the desktop. Accessed this image from the laptop and changed the color class from yellow to red. Next, I closed the contact sheet and reopened it. The color was back to yellow. Repeated the same behavior whether I was on-line or off-line with the laptop. After this I went to the desktop and changed the color class to red. It did stick and it is showing red now on both the desktop and laptop. Is it a PM issue?
