Just tried to import 76 files from 5DIV. Import hangs, showing gray thumbnails in grid mode, in film strip and black image in loupe mode. Title bar shows smart preview generation for >10 minutes without progress, cancellation not possible. Old photos were shown correctly, LR behaved very slowly >200% CPU load. Had imported other images from same camera from CF card the day before without any issue. Restarting LR helped. Anybody experiencing similar issues?
