Scrivener v. 188.8.131.52
Custom line spacing (eg. Multiple: 1.25) doesn’t display in the Options/Editing/Formatting nor in the toolbar. Instead, x1.1 is displayed.
Custom line spacing displays correctly in both cases.
I’ve previously encountered intermittently a problem where custom line spacing wasn’t being saved, instead defaulting to x1.09 in both places. I don’t know if it relates to program/system crashes (eg. if the program saves its settings on exit) or not.
