Why can’t I debug from Visual Studio 2005 after installing IE8?

I’ve just installed IE8 (final) and restarted. I can no longer debug Web Application Projects using Visual Studio 2005 on Windows Server 2003 Enterprise R2. I get the message “Internet Explorer cannot display the webpage” and then WebDev.WebServer.exe quits with no visible error message and nothing in the Event Viewer.

Why does my Visual Studio 2005 detach from the process when I start the debugger?

I’m using VS2005 to develop a web application. When I start debugging it will open the web page but the immediately detach from the process. I have found that if I close the IDE and start it back up it will work fine for a while but then start detaching again. Any insight into this odd behaviour would be greatly appreciated.
