\overline at wrong height in chrome, invisible in safari

(Apologize in advance if I'm posting in the wrong place, but I think this is a different issue than #140, which also involves overline.)

I have been working with MathJax and have a browser problem to report with the LateX \overline macro. I have a webpage which makes use of this, and it renders fine in firefox, renders but not at the proper height in chrome, and is completely invisible in safari. I searched on overline and no one else seems to have reported this. I also note that this is the case (as described above for each of the browsers) for \sqrt, which (perhaps?) invokes \overline.

Can you point us to a URL for the page in question? I'm wondering if there is an interaction with the page's CSS. You are correct that this is different from issue #140.

Wow! what an impressively quick response.

mathisasport.com is a website I run for my algebra 1 and AP Calculus
students, as part of my research in cognitive science.

Login as p4student1@mathisasport.com with a password of "1" (this is just
a test account),

then click on the "Chapter 1: Pre-Algebra review link,"
go down to "types of numbers"
click on the practice link next to the "Intermediate - overline" listing.
It will bring up a sequence of problems ("Is -1 an integer?" "Is 1/3 a
whole number?" etc. The simplest way to go through the various questions is
to simply press return without entering an answer, then press continue when
it says you didn't enter anything.)

At any rate you will come to several problems that have sqrt in them or
repeating decimals (e.g. 1/3 is the same thing as .\overline{3} ). All of
these display properly in FF, with the overline bar too low in chrome, and
with no overline bar in safari.

Any help would be appreciated.

OK, thanks. These pages work fine for me. I'm wondering if you are using OS X Lion (OS X 10.7)? This version comes with a copy of the STIX fonts, but it turns out that they don't work properly with the version of WebKit that comes with 10.7, and this causes problems for MathJax. Try using FontBook to disable the STIX fonts (you will need to disable all of them), and see if that improves the situation for you.

If that works, you can disable STIX fonts using the availableFonts array in the HTML-CSS block of your configuration.

If that doesn't work, I'll look further.

Thanks so much yet again. I am in fact using Lion. It is just as you
describe.

You have gone above and beyond, Davide, and I am not sure how to thank you
properly. I have just made a $10 donation in your honor at the MathJax
site. But my appreciation is greater than just the money.
