Problem with Cal, EventAggregator, and Application.Deactivated

I'm having an interesing problem with CAL and the event aggregator. I am attempting to publish an event when the app is deactivated or activated (application.activated and application.deactivated). Some of my modules have popup boxes that a I want to hide when the application loses focus.

this is a small code sample below

app.xaml.cs

protected override void OnStartup(StartupEventArgs e)
{
    eventAggregator.GetEvent<AppDeactivatedEvent>().Subscri开发者_运维百科be(RunIt);

    Deactivated += (s, a) => eventAggregator.GetEvent<AppDeactivatedEvent>().Publish(EmptyPayload.Empty);
    Deactivated += (s, a) => Console.WriteLine("Deactivated - in app.xaml"); 
    Activated += (s, a) => eventAggregator.GetEvent<AppActivatedEvent>().Publish(EmptyPayload.Empty);

    base.OnStartup(e);
}

Module.cs

ea.GetEvent<AppActivatedEvent>().Subscribe(presenter.AppDeactivated);

presenter

public void AppDeactivated(EmptyPayload empty)
{
    Console.WriteLine("App Deactivated - Module");
}

What happens is that when the app loses focus I get the following in the console Deactivated - in app.xaml When the App regains focus I get the below App Deactivated - Module

Any ideas on why the event aggregator would wait until the app regains focus for the event to fire.

Thanks
