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.

 Tested in Firefox 3.6.8 but did not occur there.

 IE9's debugging tool shows a JavaScript error on line 1 character 64599
 (screenshot attached).

 WORKAROUND

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