MrEd MDI on Windows

| I'm using DrScheme v206p1 for Windows.
DrScheme breaks execution at the definition of
the child frame in the following module:
(module mdi mzscheme
(require (lib "class.ss") (lib "mred.ss" "mred"))
(define parent (new frame% (label "Parent") (style '(mdi-parent))))
(define child (new frame% (label "Child") (parent parent) (style '(mdi-child)))))
The error message is:
procedure get-mdi-parent method in
C:\Program Files\plt\collects\mred
\mred.ss:1581:3: expects 1 argument, given 0
Is this a problem with MrEd or with my module?
Thanks.

This is a bug in mred.ss and it is indeed a call to the method (lambda (x) x)
without any arguments. I will file a bug report. Thanks! -- Matthias
