Another issue encountered: The paragraph formatted in Scrivener as a Block Quote doesn’t appear as such in the compiled document, but is collapsed into the previous paragraph, with the ‘>’ character preceding it. I’ve made sure to click Enter twice. I’m not sure where the problem lies.
I’ve split this over to a new thread, since this is clearly a bug in the Windows version specifically. Yes, it looks like the baked in conveniences for code and quote blocks have broken at some point. If I mark three sequential paragraphs, the angle brackets are only placed prior to the newline preceding them. They are displaced in other words, by one character. For code spans the four preceding spaces end up on the prior line as well.
I’ll get that filed as a bug, but in the meanwhile the workaround for this is the same as what I suggested for how you can set up heading styles to produce markup, in this post—you just put the angle bracket in the prefix for the Block Quote style.
