Check Syntax Question

Here's my file:

(define-struct piece (position))

(define-struct (straight-piece piece) ())


I press "Check Syntax" and here's the error:

#<struct:object:derived-from-definitions-text%>:3:32: define-struct: parent
struct type not defined at: piece in: (define-struct (straight-piece piece)
())


When I press "Execute" I have no error.

???

Here's my version:

Welcome to DrScheme, version 199.24d4.
Language: Graphical (MrEd).

Thanks.
