I am new to the E-M5 system. Just returned from a trip and want to develop my images in Lr4. The images show up in the filmstrip. If I click on an image to start developing, the images sometimes comes up or I get a gray screen. If I start to do development of an image that does come up, I see "no" changes taking place. If I go to another image and it comes up, do work, same results. Return to one I tried to work on, it has been modified (usually too far since I couldn't see what was going on). Some images that come up need cropping. Click on the crop tool and the image goes gray. Go to another image and the crop tool is open on it. I never have had Lr behave like this (it's okay with other camera (Panasonic and Nikon) images I've made). Any suggestions what's going on? (I did load the CD from Olympus and have Viewer 3 v.1.02).
