I can't comment on versions in other languages, but I have to say I regard this program as absolutely essential for managing my computers effectively with one keyboard. I have two computers and three screens, and often a MacPro is running in one window, the Mac Mini in another, and WinXP in another via Parallels - and using this program, the three work seamlessly from the one keyboard. It is fast, problems encountered with updates are looked into (and solved!) by the developer very quickly, and has given me very little problem over the years.

And it's free! It's a GREAT program in my opinion.
