I'm trying to use the Preview Web Page icon and it's 'gray-ed' out so I can't click it. I'm not using the free version, I purchased the Direct FTP software. Is there something I need to do in order to use the gray-ed icons (there are others also)? Thanks!

The Preview in the top toolbar is not for previewing your page, that is for previewing images.

At the bottom of the screen, in editor, is where I was trying. Is that still only for images? If so, once you write the html in editor, is there a place to preview what it's going to produce on the site, before publishing? Thank you
