This occurs on a new web site. It will crash when I add the scriptmanager, or if I try and edit a property of it or click in the script block.
Please contactif you need anything. Since it occurs on a brand new project I'm guessing its an environment issue, and I am not sure what you would need. firstname.lastname@example.org
