+Summary: MDI Form: Win32 when maximized adding new child causes unmaximize inconsistency
+Repro is ./ch02_Forms/MDIApplicationSample from the sample code for the 
+book "Windows Forms 2.0 Programming," by Chris Sells and Michael 
+Weinhardt, sources available from 
+Tested on SVN head on Win32, 1.2.5_5 Win32, and 1.2.5_5 Suse VM.
+On both MSFT .NET Win32 and native Win32, when the current MDI child 
+state is maximized, adding a new child just adds it as the focused 
+maximized window.  On Mono that does not occur.
+Repro steps:
+1. Run sample, and resize to decent size (say 10cm each way).
+2. Ctrl+N twice, to see two child windows (though not too fast or the 
+second keystroke will be lost :-( ).
+3. Hit the maximize control icon on "MDI Child Form2"
+4. Hit Ctrl+N.
+Expect: Still in maximized state, new child foremost.
+On Mono Win32: Children appear in cascade form!  But note the child-
+window control icons still in the menu bar (so maximized)!  But cause 
+repaint of the window, and see the maximize control also set in the child 
+On Mono Suse VM: See apparent correct maximized state.
+5. Hit Windows->Cascade.
+(Expect: no change from previous good maximized state)
+Mono Win32: See cascade patten, but the maximized control icon still set 
+in child and in MDI menu!
+Mono Suse VM: See top-most child full size, and with its maximize control 
+icon set!
+6. Hit Maximize control icon.
+Both: arranges in a new cascade (bad--two windows at top left), and 
+control icons now as expected.
