ASCIIMathML

[tz]

Hi all,

I'm totally new to TW and I'm trying to get it to work with
ASCIMathML. I've read the thread here:

http://groups.google.com/group/TiddlyWiki/browse_thread/thread/624e27ba81656485/cc0b04657da8905d?lnk=gst&q=asciimathml#cc0b04657da8905d

And I've create a tiddler with the code given and added the tag
systemConfig to it. I've also added the proper line in MarkUpPreHead.
It worked fine, more or less, but when I closed and reopened the wiki
I get this instead (this is just an example code):

<math title="a=1 "><mstyle displaystyle="true" fontfamily="serif"
mathcolor="blue" mathsize="1em"><mi>a</mi><mo>=</mo><mn>1</mn></
mstyle></math><span></span>
then
<math title="b=2"><mstyle displaystyle="true" fontfamily="serif"
mathcolor="blue" mathsize="1em"><mi>b</mi><mo>=</mo><mn>2</mn></
mstyle></math>

Anything I'm doing wrong? Anything I can do to make it work
flawlessly? ASCIIMathML worked from the word Go on my Wordpress blog
but I don't know how to make it stick in TW.

Thanks a lot.
