[plt-scheme] initalization problem w/comment-box:snip% subclass

Hi all,

I'm puzzled by the following:

	(new comment-box:snip% [with-border? #f])
generates this error:
	instantiate: unused initialization arguments: (with-border? #f) for  
instantiated class: -snip%

comment-box:snip% is a subclass of editor-snip%, no?  What's going on?

Thanks,
jmj
