OS: Windows 10 - 64bit
In "Thumbnails + Filename" view of the XnView browser, the vertical scrollbar appears a bit too late. Result is that you cannot read the filenames of the bottommost thumbnails unless you resize the file list or XnView window. The following screen video capture shows the problem: fileliste_scrollbar.wmv
Effect: Ineffective user interface
To reproduce:
1. In XnView browser set "Thumbnails + Filename" view (View » View As » Thumbnails+Details)
2. Browser a folder with some few thumbnails (e.g. 10).
3. Resize the file list that all thumbnails can be seen.
4. Make the file list a bit smaller so that you can no longer see the filenames of the bottommost row.
Actual behaviour (bug): Filenames of the bottommost row of thumbnails cannot be seen but there is no vertical toolbar for the file list to scroll.

Expected behaviour: Filenames of the bottommost row of thumbnails cannot be seen. There is a vertical toolbar for the file list to scroll down to the filenames
