Minimising window with "Always on top" attribute leaves contents in underlying window

Earle,

Any reason for the following in your patch:

@@ -893,7 +909,7 @@
  	if (s_pScreenPriv != NULL)
  	  s_pScreenPriv->fWindowOrderChanged = TRUE;
        }
-      return 0;
+      break;


The thing that strikes me as odd is that you have to return from the 
WM_WINDOWPOSCHANGED message without calling DefWindowProc (which will 
get called if you change that return to a break) in order to prevent 
Windows from breaking that message down into a WM_SIZE and WM_MOVE 
message and sending those in addition.  My worry is that you may have 
essentially found a bug in the WM_WINDOWPOSCHANGED handling that was 
fixed by allowing the WM_SIZE and WM_MOVE messages to be generated and 
handled, when we should really fix such a bug instead of accidentally 
masking its existance.

I'm not comfortable removing this change from your patch since it will 
then need to be tested again to verify that things work as expected. 
Since you have already been testing it, I figured it would be easier for 
you to do the testing :)

Let me know what to do with your patch,

Harold
