I reprogrammed the device to only send the CR and now the problem is solved. Does look like a bug or perhaps and Undocumented System Feature!I don't want it to be since they are exiting the screen the validation doesn't have to be done. It doesn't need to be validated because the user is exiting. As far as the original validation issue, I started a new project (VB2005) and tried your approach It works except that pressing Esc key still causes the validation event to fire. -- Al Reid "Terry" Hi Al, There is another property at the form level that affects how this stuff works - Auto Validate.
