    Apologize in advance if I'm posting in the wrong place, but 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 presumably invokes \overline.

    Yes you are. General MathJaX bugs should be reported on the MathJaX support site. This is for MathJaX rendering on MathOverflow, and only on MathOverflow.

    MathJax appears not to be rendering at all for me now. It works fine for example on MathSciNet, but not on MO. I am using Firefox 9 on Ubuntu. Any thoughts?

    Edit: I figured out what the problem was. I was connecting to the internet through a proxy server (the UC Berkeley library proxy, if it matters) and that was making MO not work. It seems that the problem was specific to StackExchange-type sites. I discovered it when I tried to find something on the AskUbuntu StackExchange site - there was a bar at the top saying that the page was trying to load JavaScript from another domain and that the browser was blocking it. Anyway, turning off the proxy worked - now I use the FireFox plugin FoxyProxy which allows you to switch proxies based on url patterns, so I don't have to manually change it all the time.

    Having just reached 2K reputation, I thought I'd edit a post to fix some bad latex. I got it to display in the Preview Math mode but for some reason it breaks again after I save my edit. Here's the question:
    http://mathoverflow.net/questions/88362/permutation-of-projective-limits-with-inductive-limits

    Any ideas on what could cause this?

    EDIT: Using backticks fixed the problem. Thanks to those who posted early in this thread about that particular life-saving measure.

    I don't know where to report this issue. If this is wrong place, please direct me to the right one.

    I am using Windows Vista and IE9. I was trying to print http://mathoverflow.net/questions/88368/can-a-group-be-a-universal-turing-machine.

    The math symbols like SL_3(Z) disappeared from the Question part.

    The math symbols in the first answer look ok. Have trouble with printing the second answer.

    Using Print Preview showed the same result. I'd like to know if it's my OS/browser/printer problem, or something I won't be able to fix on my end. Thanks.

    @scaaahu, perhaps you could post the printed version somewhere, so we can have a look? It's a bit hard to guess what's happening if you just say that you "Have trouble". I'm guessing that MathJax hasn't been carefully tested in IE9's print preview mode. Perhaps you might try a better browser? :-)

    "MathJax hasn't been carefully tested in IE9's print preview mode" is probably the reason.

    "Have trouble" means the errors are not consistent. The first part the print out of the second answer looked ok. Then I started to see gabbage stuff in the last part of the second answer.

    As far as I know, IE9 is the newest IE on Windows. By "better browser" did you mean Firefox?

    I am a retiree sharing the computer with my wife. There is no way I can take the computer away from her and install another browser. I might try the printing in the local library. They have Windows XP and IE8.

    @scaahu. Unfortunately I can't help identify the error, I don't have access to any windows computers. Does anyone else here have access to IE9? Also, it's perfectly possible to install a second browser in windows, without changing anyone else's experience. (E.g. install Google Chrome, easy to use and relatively excellent security, and as long as you don't set it as the default browser other users of the computer needn't even notice.)

    @scaaahu: I don't have a solution, but perhaps you can indicate if I've reproduced your problem. The computers in the Caltech math department run windows with IE 8. When I try to print to pdf, I get the following error from distiller:

    %%[ ProductName: Distiller ]%%
MathJax_Math-Italic not found, using Courier.
MathJax_Main-Regular not found, using Courier.
MathJax_Main-Bold not found, using Courier.
%%[ Error: invalidfont; OffendingCommand: show ]%%

Stack:
()


%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
%%[ Warning: PostScript error. No PDF file produced. ] %%

    Print preview (and printing on an actual printer) both work, with the following horrible result:

    awful printing

    Thanks Anton. My printout is different but similar. However, It is much better after I used IE -> Tools -> Compatibility View. I believe there are probably two issues at hand. One is IE9 vs. IE8. The other is that the printing of the question part of that thread is different from the answer part. Could somebody try the print out or print preview by using other browsers on other OS? MO is for everybody. We don't want to see different behaviors because of different browsers/OS, right?
  11.  

    Well, within limits. I'm pretty happy, unfortunately for some, to not aspire to IE "compatibility". On the other hand, this looks very likely to actually be some interaction between IE, MathJax (and possibly the way we load fonts for MathJax?), and as such the MathJax folks are likely to be interested. Can you print from any one sites that use MathJax?

    I tried print preview of couple of threads on Math SE and TCS SE. See no problem. I have not found any thread worth printing on the paper yet - ink is very expensive - I am a retiree. Will report here when I see printing problem. Any other site worth trying?
