Missing Something with Vista UAC

When you run an ASP Web site project in certain circumstances, it will refuse to load up properly if you dont sign into Visual Studio as Administrator. This seems bizarre in the extreme to me, only certain aspects such as changing the public directory structure of the website, copying the web site and changes to the database seem to be Admin activities to me, everything is should be runnable as a sand-boxed user, otherwise, what is the point of having security settings at all?
