[WP-RecentComments] language problem please help

Hello.

I used WP-RecentComments since version 1.83 and it worked great.
well, version 2.06 came along so I decided to upgrade.
The upgrade went well, but one word is not translated in to my language (Hebrew) – “on”

The word appears just after the name of the commentator and before the post name.

I chacked the .po file and the word is translated ther so the plugin get it from somewhere else.

I checked the .php file for the word but didn’t find it.

I couldn’t find the homepage of the plugin or a support forum.

here is my site: http://www.emetaheret.org.il

Please help
