I encountered it in my own application and I'm not sure I will be able to provide steps to replicate. It happens only when the VS debugger is attached. I don't have KB971092 installed, so I can't uninstall it like the other poster suggested.<br/> <br/> Regards,<br/> Pieter Breed<br/>Tue, 08 Sep 2009 22:01:38 Z2009-09-08T22:01:38Z
