I used the translation file (Japanese.txt) provided by Mr.Tilt (the same author of Japanese translation ,
http://tiltstr.seesaa.net/article/45153 ... ml#comment).
I found this error occurs when I use the above file, but this error disappears if I use the Japanese.txt file included in xwidget itself.
But this is old for xwidget 1.96, but actually it can be used for 1.96! Now I used this old file.
I think that the translation file is just a reference file and it should not affect the program behavior, and there must be a confiliction in the internal processing.
P.S.
This error occurs when I edit the items related to weather engine (accuweather), and not occur for other engines !
