/* Center a rectangle in middle of main screen. */
static void CenterRect(r)
register Rect *r;

}                                                                             
                                                                              
int StdAlert(theID)                    
int theID;                   
{                    
AlertTHndl a;        
        if ( a=(AlertTHndl)GetResource('ALRT',theID) ) {
                CenterRect(&(**(a)).boundsRect);                                
                return Alert(theID,MyFilter);
        }
        SysBeep(0);
        return(OK);
}

Something like this has worked for me.
