Hi All, I am using org-mode in a course this fall with 60 students. All of them are using org-mode from elpa. For about 10 of them, they are unable to toggle the latex-overlays; instead of getting the equations, they get empty gray boxes with an error that the png file was not created. Oddly enough, they can export to PDF just fine. I have also checked that they have LaTeX (TeXLive) installed, and it appears it is. I am able to convert tex files to dvi, and then use dvipng to make a png image. But for some reason, the toggle-latex-overlay function does not work for them.
I am at a loss to figure out what the issue is. These are Windows laptops that were preconfigured by the department. Almost all of them work fine, except for this small number I cannot figure out. Any ideas? Thanks, -- ----------------------------------- John Kitchin http://kitchingroup.cheme.cmu.edu
