In those cases, `no-val' is just an internal implementation technique, and not intended as a part of the API. In the case of `min-height' and `min-width', I think it would be better to allow `#f' as an argument, since the documented default value is not really accessible. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
