[sage-support] Re: jsMath issue and solution with error code -7
Here's a solution to my problem -- I'm pretty sure it could be useful to other people. Trying to follow the instructions above, I misinterpreted "unzip the .zip here" (i *always* get these things wrong). the way i understood it, i ended up with files like /home/ foobar/.fonts/cmr10.ttf. However, one must keep the folder that's created when you unzip the archive ! so you really need files such as /home/foobar/.fonts/Tex-fonts-15/cmr10.ttf Now it works...

are you able to select "native tex fonts" in the jsmaths preferences ? i can only use "unicode fonts", they look okay but they're not the usual Tex fonts, that's for sure.

[sage-support] Re: jsMath issue and solution with error code -7
The real problem is not the missing fonts, but the fact that sage doesn't include the jsMath image fonts that are supposed to be used when the jsMath TeX fonts aren't available. I'm sure this was not included because it was considered to be too large a component, but it really should be, as it would have avoided this problem that so many of you are having. On the other hand, if you choose not to install the image fonts, there is a noImageFonts plugin that should be used so that jsMath knows about the fact that you don't have the image fonts, and will not try to use them when they aren't there (which is what is causing the warning message). If sage uses the jsMath/easy/load.js file (and I don't whether it does or not), then there is a "noImageFonts" setting that should be changed to 1 if you don't have the image fonts. That will cause the noImageFonts plugin to be loaded at the proper time. The best solution is to install the image fonts available from http://sourceforge.net/project/showfiles.php?group_id=172663 but if you don't want to do that, then using the noImageFonts plugin is the next best thing.
