I m using PM 5 Build 15800 on an iMAC with OS X 10.9.4
I personalised the colour ratings table to fit my workflow and reviewed and rated 1400 images, all of which took the correct colour flag no problem. When i finished the folder, all images were showing the correct colour flag applied to them. However, the next time I opened PM there was a nothing there - none of the 1400+ images in my folder had any colour rating showing.
I tried rating again with just a few images - closed down and re-opened - and again, all ratings had disappeared. I have also trashed and re-installed the application but the problem still persists.
Any ideas ?
