Disabling Automatic Updates

If I set the Automatic Updater control, Behaviour Enabled = False at design time, the automatic updater still runs shortly after starting my app. Is this a bug?

No, it's not a bug. If you don't want the AutomaticUpdater to run automatically then change the "UpdateType" property. You must change it either at design time or within the constructor of your form (not the OnLoad event).

If you don't want the AutomaticUpdater to run automatically (though, I'm not sure why you would want this) simply change the UpdateType to "DoNothing".
