Good question...the problem is the behavior that adds a new record is built into the New button and there's no way to turn it off. I'll add logic to the behavior buttons that turns off the default behavior when the button's BindingFlag property is set to false, and that will address the problem in the next release. I plan to do a release sooner than later to release the localization forms anyway. If you're interested, I can get you an early release!
