I'm just starting to use this trial but I can't seem to get the photos to go into the Colour Efex window. I'm dragging the pics from the LR3 Library viewer into the icon (I have them to my left hand side of the screen). It seems to be very hit and miss, mostly miss! I can't get LR to run the application as a plug in and after I've saved the photo in Colour Efex, CEFex shuts back down and the picture reappears in the LR3 Library window. Each time I want to transfer another picture I have to re-open the CEF window and start all over again. There must be an easier way than this!!!! I haven't looked at any tutorials yet as I prefer to have a "play" first to get a feel for the app.
