Subject: Event Handlers not firing when threaded?
Is this normal? I am trying to establish multiple connections (5) in this application but when I thread my connection class, I cannot get any EventHandlers to fire.

EventHandlers only fire when not threaded.

Is this by design?

This is the test class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Matrix;
using System.Diagnostics;

namespace ChatNET
{
    class xmpptest
    {

        Matrix.Xmpp.Client.XmppClient xmppClient = new Matrix.Xmpp.Client.XmppClient();

        public xmpptest()
        {
            xmppClient.OnSendXml += new EventHandler<TextEventArgs>(xmppClient_OnSendXml);
            xmppClient.OnReceiveXml += new EventHandler<TextEventArgs>(xmppClient_OnReceiveXml);
        }

        public void Login()
        {
            xmppClient.SetUsername("xxxxx");
            xmppClient.SetXmppDomain("chat.facebook.com");
            xmppClient.Password = "xxxxx";

            xmppClient.StartTls = false;
            xmppClient.Open();
        }

        private void xmppClient_OnSendXml(object sender, TextEventArgs e)
        {
            Debug.WriteLine("SEND: " + e.Text);
        }

        private void xmppClient_OnReceiveXml(object sender, TextEventArgs e)
        {
            Debug.WriteLine("RECEIVE: " + e.Text);
        }
    }
}

When calling from my main form to test, this works fine (send/receive shows up in debug):
        private void button17_Click(object sender, EventArgs e)
        {
            xmpptest xmpp = new xmpptest();
            xmpp.Login();
        }


This does not (nothing shows up in debug):
        private void button17_Click(object sender, EventArgs e)
        {
            Thread t = new Thread(TryIt);
            t.Start();
        }

        private void TryIt()
        {
            xmpptest xmpp = new xmpptest();
            xmpp.Login();
        }
