Cecil,
How are you exiting the application? By clicking on a Button? If so, Chris's suggestion should work. By setting that button's .CausesValidation property to false, and having the button's .Click event handler execute the Application.Exit() method, the only event on the text box that should fire *is* the Leave event. If you have moved your code out of the Leave and into the Validating or the Validated event, it will not fire.
If this is not what you're doing, could you post some additional code?
