--- Comment #11 from Rafał Mużyło galtgendo@o2.pl 2008-08-25 17:19:14 --- It's a bit better even with 1.1.3 - if run in ja_JP.utf8. Now, it can viewed. If it's run in my standard locale it still misbehaves: keys with Japanese names can't be expanded (plus is visible, but doesn't work). But the exporting seems to be broken in a funny way: when I choose "Export", give a filename and press Enter, it saves an invalid export (an empty key), outputs "Success" into the terminal and quits regedit.
I'll see, if 1.1.4 will be better.
