This is like the problem that I requested some weeks ago.
On my MacPro (not MacBook Pro) I get a cleared preview of a photo when I try to delete it in PM5, but it will not be deleted on the harddrive. When I close PM5 and reopen it, the preview will be rebuild.
When I try to move it with a drag and drop mousemove to another directory it will be moved, but it's still in the original directory with the same effect that I get a cleared preview (gray photobox) and when I close PM5 and reopen it, the photo will be shown.
To delete the files in the finder (jump to it with "Reveal in Finder") works. Also to move the photos with the "Copy photo"-Function.
I tried to give all possible rights for everybody (Admin, Users, System,...) to all files of this harddrive, but that does'nt help. :-(
I tried to get a solution with the Camerabits-Support, but at this time I had no time to work on this problem.
My harddrive is partitioned and formated as Mac OS Extended (Journaled) like all my drive in my Mac pro.
