Those windows are usual by the Biblebooks if you has moved the windows.
Or on the sides of the screen.
The most easy way to restore the windows is: set it back to default.
Click on help above and "Reset e-Sword Settings".
Thanks Katoog! I found my solution. Rick also recommended RESET but it didn't work. I remember several years ago that installation also gave me these sidebars. But what I did, not knowing the outcome. was when the 4 windows were show, one by one I unpinned them and they appeared on the left side. All's well and thanks! ":-Dx
