Here is a snippet of DefDlgProc16 (DefDlgProcA/W are the same):

LRESULT WINAPI DefDlgProc16( HWND16 hwnd, UINT16 msg, WPARAM16 wParam,
                             LPARAM lParam )
{
    WNDPROC16 dlgproc;
    HWND hwnd32 = WIN_Handle32( hwnd );
    BOOL result = FALSE;

=====
Perhaps WM_CREATE handling code should be moved here:
if (msg == WM_CREATE)
{
    wndPtr->flags |= WIN_ISDIALOG;
    blah-blah-blah
}
=====

    SetWindowLongW( hwnd32, DWL_MSGRESULT, 0 );

    if ((dlgproc = (WNDPROC16)DEFDLG_GetDlgProc( hwnd32 )))
    {
        /* Call dialog procedure */
        result = CallWindowProc16( dlgproc, hwnd, msg, wParam, lParam );
        /* 16 bit dlg procs only return BOOL16 */
        if( WINPROC_GetProcType( (WNDPROC)dlgproc ) == WIN_PROC_16 )
            result = LOWORD(result);
    }

    if (!result && IsWindow(hwnd32)) <== here we check whether an app handled the message
    {
        /* callback didn't process this message */

        switch(msg)
        {
            case WM_ERASEBKGND:

Probably WM_CREATE handling should be performed even before control
is passed to an application.
