AdiIRC

With this code, OnUserMessage doesn't do anything when I write a message myself:
in Initialize():
myHost.OnUserMessage += new AdiIRCAPI.UserMessage(myHost_OnUserMessage);

and then in that function:
void myHost_OnUserMessage(IServer Server, object Target, string Message, out EatData Return) {
MessageBox.Show("myHost_OnUserMessage");
ProcessMessage(Server, Target, Server.Nick, Message, out Return);
}

It's not showing the message box, but I think it should?
