It's too big---something like 80MB unzipped (lots and lots and lots of little tiny image files; one for each character). The error message should be changed, and we ought to distribute the fonts from the jsmath homepage with Sage, so that instead of an error message, there is a nice helpful link that says something like "to get much better fonts, click here and follow these instructions, or install the jsmath-image-fonts spkg" Jason --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
