Hi,
I think I wrote some of that code, I was not trying to support
"unnumbered" environments. If I understand correctly, this is what you
are trying to get.
The attached patch attempts to solve this. Currently, `displaymath' and
`*' environments do not get numbers, I am not sure if there are other
environments that should not get numbers; please let me know if you have
others in mind.
If you (and others) could test and/or review the patch, we could
probably get it merged at some point.
Thanks,
thibault

Thanks, so it is my setting. I wounder how can I debug this?
