Mathematics tools

I think you are close to resolving your issues, but if things start going sideways on you again you can always install asciimath and use an open mimetex fallback, the google chart api* or the mimetex.dll I just posted about. I am pretty sure that will take all of about 15 minutes ;=} Remember, your fallback did not work because of your mimetex issue... not because of the text expression inserted or because of asciimath

* Mauno has posted regarding two asciimathml files he has been working with in another thread in this forum at least oen of which falls back to google chart api I believe.
