Internet Explorer stops responding when clicking on a Textblock in the DOM of a Silverlight application

STEPS TO REPRODUCE:

1.	Create a new webtest in Test Studio
2.	Record in IE 
3.	Enable Highlighting
4.	Navigate to http://demos.telerik.com/silverlight/#GridView/FirstLook
5.	Over over "Fuller" in the Last Name Column
6.	Select "text block" from the highlight contextual menu
7.	Choose Locate in DOM
8.	When the DOM window opens, click on 5-10 text blocks.


At this point the application hangs.
