I have been eager to try the new RAW Profiles released recently. But they don't seem to work within the Develop Compare function. For example, let's say I apply 4-5 profiles successively. And then I want to use the Compare function to help me choose the one I like best. The program won't let me click-and-drag previous states from the History panel. I am a long-time user of Lr and I know how it is supposed to work. You choose the Y|Y Compare function and it is supposed to allow you to click previous Develop steps and drag them into the left pane of Before/After. With these new profiles, the clicking-and-dragging does not work, or if it does at all, it is very sporadic: maybe you can drag one earlier version in, but if you try to click-and-drag another one, nothing changes in the Before panel. But substantially, it just doesn't work.
