Forget the above report, I've since done a more comprehensive one, (below):

OK, here goes.  This is dmesg output from a serial terminal, showing a boot, (quite a lot of keyboard activity during boot, not sure if this is normal or not), and a single keypress of Henkaku/Zenkaku:

My interpretation of all this is that Henkaku/Zenkaku is reporting a weird scancode, (FF), the characterset selection keys are all acting as a spacebar, and something is confusing it in to go in to a different 'mode' or something during the bashing session.

Incidently, I think there must be a secret key combination to switch the logic in this keyboard to something more Japanese - the key that I am using successfully as ALT, is labelled as follows on the keytop:

KANJI

KATAKANA

and on the front of the key, it says 'KANJI something' in green, (I can't understand all of it).

So, obviously this key is not supposed to be used as ALT, despite being in the position of ALT.

I suspect that they keyboard can emulate a US or Japanese keyboard, and it's stuck in US mode, but who knows?
