Re: Strange latex symbol behavior on html export

#+options: tex:dvipng is not good because it turns all your latex symbol
markup into images, which are inserted into the web page as images, i.e.,
it's not doing MathJax. Also bad because they don't really fit the text
lines, either. I use

# this makes MathJax work
#+OPTIONS: tex:t

I just now found this caption weirdness because I started a new .org file
with no latex symbol markup besides in the caption. Quite bizarre that when
my file sees other latex symbols, the caption symbols then render
correctly.

BTW: What does

executing Scheme code block (square)...
=> #<void>
org-babel-script-escape: ‘org-babel-script-escape’ expects a string

mean? I'm suddenly getting this in an org file which has scheme babel code
blocks, images, and lots of latex symbol markup. It first popped up when I
tried to C-c C-c a scheme code block.
