Hello,
I installed NB 6.71, upgrading from 6.70 (and upgrading many times before, probably every Release launched since 4.x).
I now noticed that duplicate items are downloaded again rather than flagged and skipped. At least when the first downloaded file was renamed or deleted; I did not try with the first downloaded file still there. Such duplicates were handled correctly as recently as 6.70.
I also believe that duplicates are not shown as such in the file list.
Is the issue known? Do you need more information?
Thanks
Jesse
