I have a web project created in Visual Studio 2005 that references several 3rd party dll's and dll's which I have created. I am using Visual SourceSafe 8.0 for version control so other programmers can work on the same project. The problem is that the dll's that I referenced when creating the project are not working for the other developers who try to get the project and run it on their machine. Visual SourceSafe renames the dll's with name.dll.refresh. Why?
