New description:

 In IE9 TinyMCE inserts a <html xmlns=""> at the beginning of a post. This
 causes any text that is entered to disappear after pressing "Update Post"

 ENV: WP 3.0.1 / IE beta 9.0.7930.16406 on

 To reproduce:
  1. Edit an existing post in IE9
  2. With the visual editor selected add a new line of text
  3. Press "Update Post"

 The text added in step 2. will disappear once the post updates.

 Console in IE9's a JavaScript error on line 1 character 64599 (screenshot
 also attached).

 ```SCRIPT438: Object doesn't support this property or method tiny
 mce.js?ver=327-1235-syntaxhighlighter2.3.9, line 1 character 64599```

 The highlighted bit of JS is:

 ```return h.item?h.item(0):h.parentElement()```

 Workaround

 Do not use the Visual Editor tab, instead edit the html directly in the
 HTML tab.

 Additional Details

 Tested in Firefox 3.6.8 but did not occur there.
