Lately, I've been noticing that thumbnails take longer than usual to populate for existing images in the Grid View. I'm using LR 5.6, Windows 7-64 Professional. Plenty of RAM and an SSD where the catalog and .lrdata reside. Any thoughts on how I might improve matters?
Also, I notice when I import images from my camera that already imported images sometimes get imported again. I've checked the box "don't import suspected duplicates" and I'm selecting "New Photos." Again, any input would be appreciated.
