Had the same problem, but the solution in this article (http://makeashorterlink.com/?E25B5199D) solved the problem for me :-). Unfortunately the link is to an archived page on Google. I couldn't find the original page! So here is the solution from the archived page:
Symptom: When saving a file in Visual Studio 2005, the entire IDE becomes non-responsive (ie. freezes) for about 10-15 seconds. Meanwhile, the save icon in the status bar is animated. After 15 seconds, the file is saved and the IDE is responsive again.
Solution: "With the help of a network packet analyzer I was able to find out what stalls Visual Studio. I found that whenever I saved a file, in my web project, Visual Studio did a DNS lookup on a host on my local network. This host was offline so although it managed to resolve it's IP address, there was no response from it. After a timeout period Visual Studio stops trying to connect to this host and goes on with it's business of saving the file.
I searched my registry to find the source of this host name and found it to be present in: HKEY_CURRENT_USER/Software/Microsoft/VisualStudio/8.0/ProjectMRUList. This registry key is where Visual Studio stores all recent projects that have been opened. In that list a project, located on a remote computer, was found. When I removed that item from the registry, Visual Studio no longer took 20 seconds to save it's Web project files."
