I created, installed, and activated an MSKLC keyboard with the three WJ
sequences described above, mapped for convenience to AltGr+Z, AltGr+X,
and AltGr+C respectively (not the Kana key, which I don't have), and had
no trouble opening or using any applications on Windows 7, including the
four mentioned above (except Zotero, which I don't use). KLC source
available on request.

I wouldn't have wasted the 15 minutes but for the continuing, tiresome
rhetoric about Windows bugs.
