Subject Re: s:Spacer (was Re: Missing Spark components)

Someone said this several messages back but I don't think everybody saw
that since people are talking about when there is a s:Spacer.

There is an entry in the spark manifest that points to mx:Spacer so
s:Spacer is mx:Spacer.

It has already shipped so you can't/shouldn't turn it into something else.
