[sage-support] updating jmol

2011-10-04 Thread MathLynx
When I downloaded and installed SAGE, a copy of jmol must have been installed for presenting 3d graphics. I would like to update this copy to the most recent version of jmol available, but I cannot find it in the file structure installed. Where is jmol? Any special info needed to update? --

Thanks, Jason, for looking into this. The worksheet has 3595 lines of text when I click on edit, and no attached files. I am not sure what you mean by typesetting, but I have not checked the Typeset box. I do, however, use quite a few latex equations in the html cells, and have a lot of plots.

Thanks, Jason! I will work on it for a bit more and keep the web console open to see if there are any error messages when the problem re-occurs. At the moment, it looks as if the refresh button helped a lot. Cheers Stan On Oct 4, 1:48 pm, Jason Grout jason-s...@creativetrax.com wrote:
