I am not able to reproduce the error you are reporting. Can you say what the error message is that you are getting in autoload.js?

There was an error with how cookies are stored by jsMath (that only seems to have affected Internet Explorer) in versions prior to 3.3e of jsMath, but I see that you are using 3.3e, so that should not be your problem. If you updated jsMath recently, it might be that the old jsMath cookie is the problem. You might try deleting the jsMath cookie first and see if that helps.

Otherwise, if you can point me to a page on your site that has some mathematics on it, I'll try it out and see if I get the same problem (I need a page with math in order to get jsMath to create its cookie in the first place). What version of IE are you using?

It is true that the javascript for the jsMath filter is loaded on the first page. The javascript for ALL filters and ALL modules is loaded at that time. The idea is that the browser will cache that javascript and so won't have to load it again on later pages. Not all of jsMath is loaded at that time (only the autoload.js and tex2math.js files, which are used to tell if the rest of jsMath needs to be loaded). It seems, however, that IE7 may not be caching the jsMath.js file when it is loaded. I'll have to look into that.
