Comment 5 for bug 1843817

I have asked one of my friend for help and am waiting for him to respond. In the meantime, I found I can use other gcin hotkeys normally, e.g. changing half/full width, switching through different languages,...etc, without the need of clicking twice but only not the ctrl+space for switching between En and other gcin languages (in my case, Mandarin). I suppose this is a useful clue that points to gcin as the problem?
