Is there javascript debugging in VS.NET 2005?

I might just be dense, but I can’t find out how to do javascript debugging in VS.NET 2005. It cheerfully informs me that “object is null or not an object” but there’s no script listing or running documents or even line information so I can’t really do much with the information.

Does anyone know if this is a feature that’s not been/being included with VS.NET 2005 or if it just works differently?
