Thank you Hokusai様
Yes i forgot to mention which software I was talking about and that is AP and Yes in my OS X settings the japanese language is activated.
I just checked one more time right now in AP opening a new document -> selecting text tool -> switch to かな through keyboard -> it keep writing in english ...
I even tried to switch the language to ひらがな from OS X toolbar and when i write on the document squared box are showing instead of the かな but if i press the space bar for the conversion it show the submenu window to choose the 漢字 ... but only square box i see.
it is funny because it should work as you said but as I check in my OS X system i can confirm that ENGLISH is my primary language and 日本語 as the second language.
So here I am with the obvious question: what to do or how to?
thanks again
cheers
