Input language stuck in English I tried to change input language by pressing shortcut commandspace and also by choosing language on the menu bar. It automatically switches to English language. 

The only way I found to fix it by rebooting the Mac.

Maybe someone knows another way?

I'm using English, Japanese and Russian on a MacBook Pro running OS X Yosemite 10.10.5.
By putting Mac to sleep(holding the power button for couple sec) and then log in again it solves the problem, and I'm able to switch languages again.
