In the study area, if I type peregrine falcon in the keyword rectangle, I get keyword 2879 which is peregrine falcon but the kanji is for the keyword sparrow
Do you mean the small kanji next to the keyword in the completion list that pops up when entering something in that rectangle, or the big kanji to the left of the story box? Also, if you have any Greasemonkey scripts installed, turn off Greasemonkey (Tools -> Greasemonkey -> Active or some such) and redo your action to see if the problem persists.
Both places, however, when I disable the greasemonkey the problem is solved. When greasemonkey was enabled I must have inadvertently made the change. So now with greasemonkey enabled I changed it back and everything's fine now. A problem about greasemonkey, though, when I start Kohii.com I get a message that there is an update to greasemonkey. I dont know how to update. Could I get some help on this?
