it seems that the windows file compimeh.409.dat could well be the store but as the file would be in constant use even if word completion nis switched off it cannot e deleted
I written a small programme that will update the wndows vocabulary fro any text list you may compile eg i made up one for using the basic4ppc so to clear the current and any erronous spellings i the vocabulary file i reset it keyboard/options/word completiion/'clear stored entries' and then run my prog loading any appropiate dictionarty i need
hopefully you will come to me with an answer but its not quite as easy as just deleting a file -- i've tried that one
many thanks
