candidate list does not open on Windows platform

[tomooda]

After several next candidate actions, a list of candidate translations should be presented.
On Mac, the candidate list shows up after a few times of next candidate, but not on Windows.

hi Tomohiro, Maybe your IME takes over the inputting characters in CJK input mode. I think IME should and needs process or edit the inputting characters when displaying candidate list. I don't know the real reason about no candidate prompter. just a reminder
