That's the first time the HandleCreated event is fired, I have a MessageBox.Show in the first line of the HandleCreated handler and this is the first time I see it. As such, how can I show you a call stack for the first time the handle is created if this is the first time the HandleCreated event is fired?
I wonder if I should hack in some Console.WriteLine statements into the mono source and recompile to see?
