When I want to inspect the UI automation elements of the Microsoft Health CUI Patient Journey Demonstrator application (http://www.mscui.net/PatientJourneyDemonstrator/PrimaryCareAdmin.htm) using the UI Spy, the host browser (both Internet Explorer and FireFox) crashes. 

The Silverlight application hosts some 1000+ UI automation elements in the Silverlight Control root and both the browser and UISpy stop working when I try to browse the UI Automation tree. UISpy refuses to start after the crash and I need to reboot my machine in order to be able to start UISpy again. I've tried some other automation clients such as Narrator as well and these also crash both FireFox and Internet Explorer.

Internet Explorer Error: Unhandled exception at 0x764942eb in iexplore.exe: 0xE0434352: 0xe0434352.

Hi ! 

The fix for this bug is now available in the SL2 GDR. Users can get it today by installing Silverlight from http://www.microsoft.com/silverlight/. It will take a few more days for the update to become available on Microsoft Update.

Thanks, Stefan Wick
