You must be kidding: I replied to that opening message.  It says:

    I currently find myself having to use Windows/XP for a short while.
    My first action was to install cygwin and rebuild the latest CVS Emacs
    snapshot.  Much to my chagrin, it would appear that the ancient
    Windows right Alt/Meta key problem still exists (the right Alt key is
    NOT a Meta modifier key as is the left one).

There's nothing here about language switching, just about rge right
Alt key.

I don't see this on MS-Windows.  Is this supposed to work on Windows?
Note that the opening message clearly talks about Windows-related
issues.

The opening message wasn't from Lennart, it was from Paul Michael
Reilly.

That's another issue altogether, let's not add to confusion.
