Today sees a new sanitizer release as part of
which should fix the issues you have seen since the last release.
This release also changes some of the URL path and HTML encoding for compatibility with webforms.
This will be the last release with a sanitizer - the HTML parsing engine is too old and fragile to maintain. Further releases will be updated or new encoding types.
Source code will follow tomorrow once I have a new VM with the SVN bits up and running.
