I downloaded the dictionary from
this thread. That works fine when I look up words in a book I'm reading but when I try to then type anything that's when I have a problem, I really think it's a bug in the pocketbook.
p.s. Thinking about it, I see what Kacir is saying. The dictionary I have was created for the PB360. So switched to the regular (Ukrainian or Russian, idk) dictionary and the keyboard was right.
