Silverlight, OutofBrowser localCommunicationAPI problem

Question

Hi, I've encounter the following problem: I have two very simple applications, that only contain one LocalMessageReceiver and one LocalMessageSender per application. Everything is working fine when debugging or starting from the local test page, even after insalling the out of browser application locally.

Also it is working when starting from our hosting server, when running in borwser.

But after installing such a application (hosted from the https site) - the communication work only, when sending message from installed application to one in a browser, the opposite communication is not possible. Also when running two installed applications - there is no communication.

Do you have any idea, where is the problem?

The receiver is created as follows:

receiver = new LocalMessageReceiver("Longinus_EB041E0F-1E26-4F17-B337-1C090D09EE24", ReceiverNameScope.Global, LocalMessageReceiver.AnyDomain);
            receiver.DisableSenderTrustCheck = true;
            receiver.MessageReceived += new EventHandler<MessageReceivedEventArgs>(receiver_MessageReceived);
            try
            {
                receiver.Listen();
            }
            catch (ListenFailedException ex)
            {
                MessageBox.Show(ex.ToString());                   

}

and there is of course no error when starting listening.

The senders are created as follows:

this.sender = new LocalMessageSender("Silvia_61BDA4E0-E5AF-4371-8B35-9310C313C15A", LocalMessageSender.Global);
                sender.SendCompleted += new EventHandler<SendCompletedEventArgs>(sender_SendCompleted);

Thank you for any help!
