I am running Logos v 26.0 on Windows 11 22H2 (build 22621.1848) on an HP i7 laptop. I suddenly cannot highlight. I was trying to highlight this passage in Augustine's City of God and I can select the text, the selection menu appears, but when I click the highlight button nothing happens. By "nothing happens" I mean that the menu disappears, the text remains selected, but it is not highlighted. I then tried it with a passage in Christopher Watkin's Biblical Critical Theory and thought I'd try a Bible as well, and I can't highlight in NA28 either. I restarted Logos, and it didn't make any difference.
I've attached logs here.Logos 230706.zip
I have recently reported a similar issue with the iPadOS version so wonder if something has been broken in highlighting in general. The one thing I haven't tried is rebooting my PC. I will try that and post in here if it works after that.
