Thanks for the explanation. Indeed, the "dictionary cascade" feature does not work any more. But I don't miss it that much. I've got a bunch of 5 English related dictionaries installed now. Among them English-Chinese and English-Japanese (well, they might be useful one day, you never know). With the old firmware, it happened to me many times that an English word was not found in the default "Oxford" dictionary but it was found in some of the remaining ones. So I was getting perfect explanations in Chinese and/or Japanese. Needless to say, I don't speak any of these languages.
I think one would need an additional option in the "Settings" -> "Device Options" -> "Language and Dictionaries" -> "Dictionaries". Not only the language specific "default dictionary" setting is needed but also "enable dictionary for automatic searches" (so that one could "unmark" dictionaries that use languages which one doesn't really speak).
I believe I miss another feature very much (it was never present in any firmware). When a word is not found in the dictionary, one simply gets the message "No definition found" in the "small" dictionary definition window. When one then clicks "More", the "Open Dictionary" button is inactive (i.e. "greyed out"), so there's no easy way to enter the dictionary and search for a word manually. I would like the search engine to automatically open the dictionary on a word which is as much similar to the wanted one as possible (for example, as many initial letters as possible should "match").
On second thought, what I miss the most is the JBPatch ... in particular the possibility to reduce reader margins (and maybe enable hyphenation) ... KPW1 5.3.4 firmware was the last supported version.
