problem with starting threads

[kokon]

Hello, I`ve got to subs like this (second one doesnt want to start thread):
-------------------------------------
public void button4_Click(object sender, EventArgs e)
{
this.demoThread = new Thread(new ThreadStart this.ThreadProcSafe));
this.demoThread.Start();
}
public void process2_Exited(object sender, System.EventArgs e)
{
MessageBox.Show("Exited2");
this.demoThread = new Thread(new ThreadStart(this.ThreadProcSafe));
this.demoThread.Start();
}
---------------------------------------
First one started by button works ok.
But the second one which is started by:
--------
myProcess.Exited += new System.EventHandler(kol.process2_Exited);
--------
doesnt work. I can see the MessageBox, but after that- silent.
Please help
