Misplaced Property Sheet buttons

[Peter Åstrand]

I'm debugging a problem where the standard buttons on a property sheet are 
misplaced. The application is Magna Cura. The screenshot 
http://www.cendio.com/~astrand/wine/62-tab-size/unpatched.png demonstrates 
the problem: The buttons are only partially visible. It turns out that the 
parent window for the Buttons changes size several times. The height is:

228
95
466
436
450

The PROPSHEET_AdjustButtons function, however, is only called in 
WM_INITDIALOG, so the buttons are positioned based on the height 466, and 
never repositioned. What's the proper fix for this? I've tried this patch:

--- propsheet.c (revision 13243)
+++ propsheet.c (arbetskopia)
@@ -3828,6 +3828,13 @@
         return TRUE;
     }

+  case WM_WINDOWPOSCHANGED:
+      {
+         PropSheetInfo* psInfo = (PropSheetInfo*) lParam;
+         PROPSHEET_AdjustButtons(hwnd, psInfo);
+         return FALSE;
+      }
+
     default:
       return FALSE;
   }

This solves the position problem, but instead the Help button disappears. 
See screenshot
