Please take a screenshot or picture for me. I want to ensure I understand if you are actually seeing two pages, or if you are just seeing two columns, which is entirely different and is controlled by the Settings->Text File Settings->Use Multiple Columns option. If you auto-size the font with a maximum font size of 60, for example, the text should always take up the entire width of the page which is the entire width of the screen when using any display mode other than the two page display mode.
Thanks,
Mike
