On Windows 10, Scriv v3.1.4.1.
Revision mode works fine in the main editors. Format > Revision Mode > First Revision launches the Enter Revision Mode? info box. Press OK and I’m in Revision Mode. New text is in the appropriate color.
However, in a Quick Ref panel, trying Format > Revision Mode > First Revision (or any revision) does nothing. No info box is displayed, Revision Mode is not enabled, and new text is in the normal non-revision color.
If I enable Revision Mode in a main editor, then it does enable it in the Quick Ref panels, so that’s a good workaround.
I see this behavior in my own projects as well as in the Tutorial.
Please let me know if you have any questions.
Best,
Jim
