I must have been asleep when this 'feature' appeared. I downloaded the latest ASP.Net MVC Storefront sample today from Codeplex. I then dragged the downloaded Zip file over to my project folder, extracted it and built the project. When I tried to run some of the unit tests - I got "Failed to queue test run me@myserver2008-09-23 15:20:05': Test Run deployment issue: The location of the file or directory '\...\.config' is not trusted.

A quick Google and I found the problem. There's a new attribute on files that you download from the Internet. Right click on the Zip file, choose Properties.. and you'll see the window as shown, with a message that says: This file came from another computer and might be blocked to help protect this computer. You need to click the Unblock button before you extract the contents of the Zip file... and then everything works fine...
