However, it doesn't seem to work when entering TeX in the Quiz choices of a Multiple choice quiz.
It still doesn't work for me. I'm new to the whole thing so maybe I did something wrong somewhere else... I have the same expression typed into the question area and in the quiz choice area. It shows up the way I expect it in question area but not in the choice area.
I have the expression "" in both areas.
Looks good - what screen capture software is it? Do you crop/highlight separately or within the product?
