I've noticed that sometimes, whilst I'm typing away using romaji mode, my punctuation keys suddenly get remapped to what I'm assuming is the american, british or whatever layout. For instance, brackets/parentheses which are usually assigned to shift+8 or 9 become shift+9 or 0 I usually remedy the problem by tapping the kana and romaji input buttons till it sorts itself out. If that doesn't work, I turn on and switch to US or British, and then turn it off again and switch back to Romaji. Can anyone explain why this might be happening? I think it's happening across all apps, but it's most noticeable when i'm switching between Japanese and Romaji input in Word. Thanks guys!
