Every since upgrading to windows 10 I have detected a bug which annoys me immensely. When I use the (old) Windows Photo Viewer to check out my files, it seems browsing the pictures does not take into account the file ordering I selected in explorer. I'll try to explain:

* say I have a folder with 10 .ARW files and 10.JPG files (raw + jpg), I setup the folder so it groups the files by type

* when I now doubleclick one of the jpg files and use the arrows to browse through them (using windows photo viewer) the viewer always shows me the raw file > jpg file > raw file > jpg file, which it should not (it should browse through the jpg files, like it did in windows 8)

Any idea how to fix this? Strangely enough, this does not happen when using the default windows photo-app (which I dislike).

Also, I would like Windows10 to remember that when I use a folder under "pictures", to always group by file type. Somehow I cannot seem to make it do that.
