Output View window vertical not horizontal

Using Plato 4.51. Somehow I've got my output window on the left side, vertical position. Can't get it back to bottom horizontal, where God intended it to be. I know it must be something simple, but can't figure it out. Thanks in advance for your help. - Mike Cheek, Houston

If you can right click on the caption bar then select 'Floating' and then drag the window to the docking position.
