OK, Just tried it with he default Windows Photo app. Selected 80 photos about 2GB and right click, copy, then open another folder and right click......hang. It locked up windows explorer, folder went to not responding. Closed folder, explorer recovered, open folder again, right click paste and bam they were there. Looks like a problem with a crappy photo app. I use it for viewing and thats about the end of it. If I want to move folders or images around I do it from windows explorer and use tera copy. For editing I use Adobe CS5 or Lightroom.
