Vertical bar at end of math entry

[Kiwi1]

When I enter math like \(x^2\) I often get a vertical bar shown to the right of my math when I print the document or view it on screen. Something like this: \(x^2|\)

I get this both on this site and also when I write HTML using mathjax.

When I preview this post I don't get the vertical bar. It seems a bit random.

Am I doing something wrong? Can I reliably avoid what looks like an edge on the math image?

What browser are you using?

The reason I ask, is that MathJax makes extensive use of HTML/CSS, both of which are handled client-side, and different browsers handle this in different ways.

I was using Chrome v49. I just upgraded to Chrome v50. I have tried opening my document with IE11 and that was fine.

In Chrome (either version) if I open my file then all is fine, when I scroll to the bottom of the doc and back to the top the bars appear.

I just looked at a page here with a great deal of $\LaTeX$ on it using Chrome 50.x and didn't notice the issue you reported. Can you give me a link to a page here where the issue occurs for you?

Thanks, I think I have found it.

I was working on an HTML file on my local hard drive. Sometimes I use Mathjax off the web and sometimes from a copy on my HDD.

It turns out I get the bars when I use the HDD copy. So I downloaded a fresh copy of MathJax and so far it seems to be problem solved.

This worked:
<script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>

This did not until I updated MathJax:
<script type="text/javascript" src="file://c:/mathjax/mathjax-master/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
