The green button works as you say! Thanks. It's strange though, because before I press it, I can double-click the bottom right corner to drag and change the width of the window, but not the height, but after I press the green button and the window becomes slightly less high to above the dock, the window also becomes the entire width of the screen, and if I try to double-click the bottom right corner to drag the window to be less wide, it automatically makes the height full-screen below my dock again!?! What the heck. But still, I'll take a full-width window above the dock than a full-heighth window below the dock that change change widths, so it's an improvement!
Yes, all of my books are epubs. I searched as you specified and only the non-deleted books show up. I'm really thinking the other titles are gone for good.
I just think it's so strange how when it synced and deleted the books, Reader for Mac still took over the
titles of the deleted books, and left the titles of the deleted books on Reader Library as well, but somehow deleted all the contents and the files. I don't even see how this is possible since I thought all deleted files should go in trash, which I checked and they're not, but somehow the software did delete them. And when I finally found where the books I still have are located in the Reader software in the Finder on my Mac, only the non-deleted books show. So it just makes me wonder - where are the titles that still show up coming from?!? I'm glad they're there so I can at least take proper inventory of what's been deleted, but they're just phantom titles on the software with no associated files apparently.
