In the immortal words of...someone, "It Works For Me" (TM).

In particular, the following code compiles under both Mono 1.1.1 and

	// delegate casting...
	using System;

	delegate void PInputEventHandler (object sender, EventArgs e);

	class Test {
		public static void Main ()
			Test t = new Test ();
			Delegate d = new PInputEventHandler (Handler);
			((PInputEventHandler)d) (t, null);

		private static void Handler (object sender, EventArgs e)

Your code should work.
