For some reason the scrollbars in both the text editor and the document pane are gone. Yesterday, they were there, but were extremely thin. I’ve tried my Mac preferences and made scrollbars “always visible”, but I still can’t see them. This does, however, make my document window shift slightly when I toggle this setting. So something is happening, but the scrollbars still aren’t showing up. I’ve tried a lot of basic troubleshooting including re-sizing my Scrivener window, but I’m wondering if there’s a setting somewhere in Scrivener that mysteriously got toggled. I don’t have this problem with any other app.
First, I would try seeing if the problem is also visible in another project, like the Interactive Tutorial from the Help menu. If so, then a quick reinstall is probably in order. It could be your installed copy is damaged.
