OK, a couple of things.
1) I notice you still have the code in the Leave event, maybe you've removed the delegate to it so it no longer fires, but I just wanted to point that out.
2) When I tested this, I did an application.Exit() from the Button click, rather than a this.Close(). Since you are using this.Close(), then instead of setting the .CausesValidation property to false for the button, you need to set the Form's .CausesValidation property instead. That should take care of your problem.
