Exceptions when importing DocX files

[ANN]

We are trying to load help documents from the server into a RichTextBox. We were going to use HTML files but the image links caused cross domain issues. I saw the post : http://www.telerik.com/community/forums/silverlight/richtextbox/initialize-richtextbox-with-docx-file.aspx so we decided to try switching to docx files. We upgraded to the Nov 2010 release (2010.3.1110.1040)  and picked two sample docx files that were created in Word 2007. One has just one small image in it (20kb) and the other is 11 pages (299Kb). The small document loads but larger docs all throw exceptions.  Is there only limited support for the docx format?

When we load the larger docx file we get this exception:
System.FormatException occurred
  Message=Input string was not in a correct format.

Hi ANN,

The Docx format is quite complex, and not all its features are supported for now, but in the import process parser silently ignores document structures it doesn't recognize - so the behavior you identified is not normal.
Could you please open a bug report ticket and send us a sample docx file that throws the specified exception, so we can investigate the problem further?
Do not hesitate to contact us again if you experience any other issues.

Sincerely yours,
Boby
