+Summary: Control.OnClick do not supply a MouseEventArgs
+
+Description of Problem:
+
+The method
+protected virtual void OnClick (EventArgs e);
+doesn't provide a MouseEventArgs when overridden. This makes it impossible
+to use it to get the mouse clicks.
+
+Steps to reproduce the problem:
+1. Compile this snippet inside a winform application
+
+protected override void OnClick (EventArgs e)
+{
+    MouseEventArgs mea = (e as MouseEventArgs);
+    if (mea == null)
+        Console.WriteLine ("Expected MouseEventArgs but got " + e.ToString ());
+}
+
+2. Click on the form
+
+
+Actual Results:
+EventArg is empty (not null) and cannot be cast to a MouseEventArgs (like
+on MS Fx). So the console shows
+Expected MouseEventArgs but got EventArgs
+
+Expected Results:
+I should be able to cast the EventArgs into a MouseEventArgs and get the
+click position (i.e. no message on console).
+
+How often does this happen? 
+Always
+
+Additional Information:
+* Only tested under fx 2.0 and Mono SVN.
+* Changed my code to overriding OnMouseDown (which use MouseEventArgs)
