MSHTML and IHTMLDocument2 and "A Runtime Error has occurred"

[GHS]

I'm writing code to parse a specific website and decided to use MSHTML to
help (instead of regular expressions). The parsing code is complete - looks
very nice if I say so myself. :-)

The problem I have is setting up the doc itself. Here is a code snippet of
where the problem shows up:
FileStream file = new FileStream("c:\\day.html",
FileMode.OpenOrCreate, FileAccess.Read);
StreamReader sr = new StreamReader(file);
string html = sr.ReadToEnd();

IHTMLDocument2 doc2 = new HTMLDocumentClass();
doc2.write(html);
doc2.close();

I'm reading from a file in this stage of development. I simply went to the
site, did "view source" and saved it. I'll handle logging into the
site/etc. after I fix this.

The doc2.write(html) causes the familiar dialog box:
Error
A Runtime Error has occurred.
Do you wish to Debug?

Line: 16
Error: Object expected

<yes> <no>

I know I can turn that off, but my concern is "why is that happening"? I'm
90% sure it's because there is script code in the html. I am perfectly fine
having the script code NOT execute. The html I care about doesn't rely on
it. I don't want to force users of my code to have to turn off that dialog.
I'd rather have the dialog not come up. The doc object contains the correct
content and other than having to press the no button everything works fine.

Any suggestions?
