Alexander Taylor氏によるOS/2版wnn、WnnIM for OS/2が更新されました。
これを使うとArcaOS英語版でも、ソフトに対して直接日本語入力が可能となります。

New in this release:
・Fixed problems locating the FreeWnn configuration files (which caused kanji conversion to fail with an error message under some conditions).
・The UI is now available in English or Japanese (depending on your %LANG% setting and codepage).
・Greatly improved the size and positioning logic of clause conversion overlay text.
・Slightly better compatibility with Japanese (106/109 key) keyboards.
・Better handling of unfinished 'N' kana input at the end of a clause.
・Now includes custom romkan (romaji to kana) conversion tables, which fix a number of issues with the romaji conversion in general; romaji input by default now behaves closer to other platforms.
