EDIT: I realised my title (without the parenthesis) might bring an onslaught of opinions - free - of course. That might be more than I require just now

Does anyone have any experience with the free version of Anime Studio - the Japanese one:
http://animestudio.jp/free.html
It is dated 2007 but I wonder if it is doing anything different than 5.6 or 6?
It is only a 4mb download but I am always reluctant to install software unnecessarily - way too much clutter in the registry already

thanks - arfa
