[plt-scheme] MrEd from command line

In DrScheme version 200,
(send (instantiate dialog% () (label "title")) show #t)
shows an empty dialog. But, from the DOS prompt,
mred -e (send (instantiate dialog% () (label "title")) show #t)
displays an error message : "#f::1: read: expected a ')'"
Why is this happening?
