After years of Calibre usage, I'm having a problem in Edit Book that was reported by some a few years ago. I inadvertently undocked the File Preview window. Double-clicking the File Preview window title bar does re-dock the window. But it docks it above the File Browser, not to the right of the html window as it always has before. Dragging it anywhere else just undocks it again.

How can I get it to its default position where it's to the right of the html window and as fully vertical as the html window is? There's not enough space vertically for both the Preview and File Browser.

EDIT: I finally got it. After dragging the File Preview window around for a long time, but always missing the sweet spot, I found a location at the upper right of the Edit Book window below the toolbar that got it back where I wanted it. Maybe this will help someone.
