This is what mine looks like.  Since I am new to SubClassing the frame 
window, am I doing something wrong?

LRESULT CALLBACK WndFrameSubProc (HWND hwnd, UINT message, WPARAM wParam, 
LPARAM lParam)
{
   HDC         hdc, hMemDC;
   RECT        rect ;
   BITMAP      bm;
   long        x,y;

       switch(message){
        case WM_ERASEBKGND :
                //CallWindowProc(pfnOldWndProc, hwnd, message, wParam, 
lParam);
                //InvalidateRect(hwnd, &rect, TRUE);

                DefWindowProc(ghFrame, message, wParam, lParam );
                GetClientRect(hwnd, &rect);
                hdc = (HDC) wParam;
                GetObject(ghBitmap, sizeof(BITMAP), (LPSTR) &bm);
                hMemDC = CreateCompatibleDC(hdc);
                SelectObject(hMemDC, ghBitmap);

                if (bm.bmWidth < rect.right - rect.left)
                   x = rect.right - rect.left - bm.bmWidth;
                else
                   x = 0;

                if (bm.bmHeight < rect.bottom - rect.top)
                   y = rect.bottom - rect.top - bm.bmHeight;
                else
                   y = 0;

                BitBlt(hdc, x, y, bm.bmWidth, bm.bmHeight, hMemDC, 0, 0, 
SRCCOPY);
                DeleteDC(hMemDC);
                return 1;
         case WM_DESTROY: SetWindowLong(hwnd, GWL_WNDPROC, 
(LONG)pfnOldWndProc);


        default : return CallWindowProc(pfnOldWndProc, hwnd, message, 
wParam, lParam);


   }
}

Frame Window Proc
==========================================================
     case WM_MOVE:    DefWindowProc(hwnd, message, wParam, lParam);
                      return(1);
     case WM_SIZE:
                      DefWindowProc(hwnd, message, wParam, lParam );
                      GetClientRect(hwnd, &rect) ;
                      MoveWindow(gHwndClient, rect.left, rect.top, 
rect.right - rect.left, rect.bottom - rect.top , TRUE);
                      //InvalidateRect(gHwndClient, NULL, TRUE );
                      return(1);
                      break;
