A random WSS 3.0 SP2 issue

I found this by accident:

http://support.microsoft.com/?id=909455

"Document library event handlers that use object model code without explicit impersonation fail with the "Cannot complete this action" error message after Windows SharePoint Services Service Pack 2 is installed"

"All document library event handlers must perform explicit impersonation to use Windows SharePoint Services object model calls."

"This behavior is by design."

I'll just leave it at that...
