Hi, I'm testing LyX 2.0.4 on a Mac, trying to get xeCJK, XeTeX, etc. to work. One problem I've never been able to solve is how to change the language in Document Settings... on my installation, no matter what I do, "Language Default" is selected, but is greyed-out. The option button, where I would expect to select UTF-8, is also greyed-out.
What must I do to enable modification of these options?
