Hi Hayo,
It told you that there were always 'batches remaining' in the 'Catalog Metada Updates' task bar.
So I suspected something wrong in the catalog databases, so I have deleted all catalogs, including the 'default' one created automatically.
I have created a new (and only one) catalog, and now scanning goes to completion at least after the first scan (all tasks bars green) AND the Organizer panel is behaving as expected, for sometimes then hangs after the next scan (with batches remaining in Catalog Metadat Updates'.
So the probem is with the metadata update function, perhaps due to something special in my data (mix of pictures NEF, RW2, JPG ...): when there are batches remaining, the catalog hangs
For me, the problem is partially closed (this is a beta version), but I can investigate further if this could be helpful for the development team.
Thank you for your help
