Hi All,

I catch an unhandled exception if the following html code is passed
into MarkupServices::ParseString(). I've verified my source code with
other HTML documents with no problems (and the NULL terminator is
present in memory). I also ran the page which contains the frameset
through HTML Tidy to verify it's correctness.

Any ideas?

Jeff
