Thanks for the info on mimetex and TeX filtering in Windows 2003. It continues to be one of my biggest hurdles. I'm looking at jsMath. In any case, I notice 2 mimetex.exe files. The one you mentioned and the one that is on CVS - one is 423kb and the other from the download site you listed and suggested is 322kb. What is the difference between the files? Why would one be on CVS and the other on download.moodle.org? Any clarification you (or others) might have would be appreciated. Peace.
