Debugger Starts then Stops....no errors or warnings

Hi Guys,
Just installed the final of VS 2005, played around and then went back to working on a project I have in VS 2003. Only to find I can't debug it anymore! The project is a c# assembly that is debugged by starting outlook 2003. Now i can compile everthing fine. I can run outlook and all my assembly works fine without debugging........but when i try to debug it inside visual studio the debugger starts up, outllook starts, then all of a sudden everthing stops and i am back in visual studio staring at a blank debug window....no warnings, no errors, nothing.
Has anyone got any ideas? I can debug executable projects and web projects with IE, just not assemblies when another program needs to start. I know it has something to do with VS 2005 or .NET 2.0 cause when i uninstalled them it went back to working.
Thanks in advance.

This is a known issue. When a native application (in your case, Outlook 2003) loads a managed assembly, it will use the latest version of the CLR. In this case, it will use CLR 2.0. However, the Visual Studioi 2003 debugger is unable to debug applications that run on CLR 2.0.

To fix this issue, you can use an application configuration file to tell Outlook to load CLR 1.1 instead of CLR 2.0.
