I'm using mac mini as remote controlled server, and using Windows 7 PC as a client. When I types some characters in Korean, sometimes, the input source is changed to English even if the input source shown title bar is still Korean. And sometimes, the input source is Korean and typed in Korean, but some keys delete the character typed just before. The OS of my mac mini is El Capitan, but when I used Yosemite, I had same problem. Please give me some solutions or information about that. thanks in advance.
