Viewing thumbnails in main window

In the Views dropdown for List, Details, Large and Small Icons, Thumbnails, and Tiles, the Thumbnails selection is ghosted. The person that showed me this program (thanks!) had viewable thumbnails.

How do I set my smartFTP to show thumbnails, or am I doing something wrong?

Thanks!

Hello ..

Only the Local Browser can show "Thumbnails" at this time.
