In organizer/browse when filename is selected as the sort order it is sorting as follows 1,10,11,12,13,14,15,16,17,18,19,2,20,21 etc - you get the idea. Of course it should be 1,2,3,4 etc.
The sorting by filename is correct in Navigator, however, it is always incorrect in Organizer/Browse. If I select capture time then the files are sorted correctly by both capture time and filename. Restarting or reinstalling makes no dufference.
