JOe actually it is available in list view. I use only list view 95% time; Thumbnails view 5/ %, and never use Column view. . Found the solution: You go to menu, list view, and it's there. Hide or show preview . Though should also be in preview options but is not for some reason.
Thanks for posting that, but I"m unable to duplicate it.
For future reference, would you please post a screenshot of the menu to which you're referring.
Thanks.
