Refocus plugin- windows OS

Edit
fixed now!..(was a problem for DA automatically renaming uploaded file, fixed now)

It is a plugin for Gimp ( [link] ) this is the version for windows xp-vista and work well with last gimp 2.4..
Quite useful plugin but almost impossible to find (more easy find the source code or the Linux version )

I stumbled upon its link browsing Japanese websides but few in the US or in Europe do it..even less may understand the meaning of Japanese ideogram

So i thought was a good idea to mirror here where even who do not understand Japanese may have a chance to find it !!
