ShutDown event won't fire

VS2005 Beta2

don't know why what's wrong with my project, shutdown event won't fire. I created a new project, shutdown event fires.
This project was in Beta1, it is not totally new beta2 project. What could be wrong? I compared every file I can think of, no difference.

OK, I just figured it out, I was using END statement to close the application, that is the reason.

By END do you mean Environment.Exit?

NO, literal "END"

Okay. Just had a look up the help, and the End statement just calls Environment.Exit underneath, this is what it said:

"The End statement calls the Exit method of the Environment class in the System namespace"
