OK, thanks for the detailed description of what is happening. Now
this makes me think that this IS a jsMath bug, and not an improper
image font installation. If the image fonts are working in Firefox,
then they are installed properly.
The error you are getting about jsMath thinking that you are trying to
load jsMath from a different server is the key, here. It is not able
to load ANY of its extra files (including things like the control
panel, and IS-specific customization files) because jsMath is confused
about where it was loaded from. What I suspect is the problem is that
the port number is confusing jsMath in IE. Every browser except IE
"normalizes" URL's so that they include the protocol, host, port
number, etc, so when jsMath looks to see where it was loaded from so
that it can load additional files, that information is all right
there. But in IE, the URL is left as it is originally in the HTML
file, so jsMath must reconstruct it itself. It looks like it is
leaving out the port number, and so jsMath is looking for its
components in the wrong place, and so not finding them.
As an experiment, if you could insert the lines
<script>
jsMath.Autoload = {root: "https://99.240.209.8:8000/"}
</script>
to the font test HTML file just before the script tag where jsMath.js
is loaded, and then see if that makes it work in IE7, that would tell
us if this is really the problem.
In the meanwhile, I will work on that part of the jsMath code and get
it to include the port number.
