Any suggestions as to why calling this more than 4 or 5 times with 4 or
5 TE windows open hangs the system (not even a bomb)?

#define	SAVE_WIDTH		250
#define SAVE_HEIGHT		110

int HandleQuitOrSaveDialog(void)
{
    Handle      itemList;
    DialogPtr   saveDialog;
    Rect        boundsRect;
    int         itemHit;

    SetCursor(&arrow);
    itemList = GetResource( 'DITL', SAVE_DITL_ID );
    
    SetRect ( &boundsRect, (screenBits.bounds.right - SAVE_WIDTH) / 2,
                           (screenBits.bounds.bottom - SAVE_HEIGHT) / 2,
                           (screenBits.bounds.right + SAVE_WIDTH) / 2,
                           (screenBits.bounds.bottom + SAVE_HEIGHT) / 2 );
    
    saveDialog = NewDialog( NIL_POINTER, &boundsRect, NIL_TITLE, TRUE,
                dBoxProc, MOVE_TO_FRONT, NO_GO_AWAY, NIL_REF_CON, itemList );

    FrameDItem( saveDialog, SAVE_BUTTON );

    ModalDialog( NIL_POINTER, &itemHit );
    
    DisposDialog( saveDialog );
    ReleaseResource( itemList );
    return( itemHit );
}
