Yes. Early versions of FBtoC had a markedly incomplete implementation of the old-style 'on dialog' event handling. It was assumed that most apps would need rewriting to use CarbonEvent handlers. Later we found it possible to synthesise old-style events quite accurately. All windows have the kWindowStandardHandlerAttribute, whether you ask for it or not. Robert P.
