 All that happens on Windows XP SP1 using Mono 1.1.18. Don't know if it
 is a Linux issue too.

+A few notes on this so I won't forget...
+
+#1 is a problem related to the default focus of a control inside a
+container, see bug #79384.
+
+#3 is a few things:
+
+ - the messagebox form is getting created and added to the
+Controlcontrols list and queued to the toplevels list, but when the
+user clicks Ok, the MessageBox is getting hidden and dequeued, but not
+getting removed from the Control.controls list. This causes
+MessageBoxes to pile up on the Control.controls list, so when the
+activation messages are sent, these get the last activate messages
+after the main app form
+
+- the Application.MWFThread.Current.Context.MainForm is getting
+changed when the MessageBox is shown, but it's not getting reset back
+to the main app form when the MessageBox is closed, so that messes the
+focus stuff
+
+- The MessageBox is not really getting destroyed, it's just getting
+hidden, though it's never recovered back
+
+- According to the msdn docs for EnableWindow:
+"if an application is displaying a modeless dialog box and has
+disabled its main window, the application must enable the main window
+before destroying the dialog box. Otherwise, another window will
+receive the keyboard focus and be activated"
+
+This last point is the main problem once the others are solved.
