           Product: Wine
           Version: 20050628
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED

         Component: wine-gui
        AssignedTo: [e-mail]

Took the Petzold-Code describing MDI, modified it to have a child window opened
right at startup (wm_create of the frame window proc has been modified):

[original petzold code: mdidemo.c]
[...]
     switch (iMsg)
          {
          case WM_CREATE :          // Create the client window

clientcreate.hWindowMenu  = hMenuInitWindow ;
               clientcreate.idFirstChild = IDM_FIRSTCHILD ;

hwndClient = CreateWindow ("MDICLIENT", NULL,
                              WS_CHILD | WS_CLIPCHILDREN | WS_VISIBLE,
                              0, 0, 0, 0, hwnd, (HMENU) 1, hInst,
                              (LPSTR) &clientcreate) ;

/********** new ********/
           mdicreate.szClass = szHelloClass ;
           mdicreate.szTitle = "First Startup Hello Window" ;
           mdicreate.hOwner  = hInst ;
           mdicreate.x       = 10;
           mdicreate.y       = 10;
           mdicreate.cx      = 300;
           mdicreate.cy      = 100;
           mdicreate.style   = 0 ;
           mdicreate.lParam  = 0 ;	       
           hwndChild = 
    	 (HWND) SendMessage (hwndClient,
    			     WM_MDICREATE, 0,
    			     (LPARAM) (LPMDICREATESTRUCT) &mdicreate);
               /***********************************************/

return 0 ;

case WM_COMMAND :

On Windows, child window is showing up with its full size, on linux/wine this
child window has zero size.
