Input Sources Menu not working I recently updated to Sierra.  Now the Input Sources Menu isn't working.  My 2 source are listed (US &amp; Unicode) but selecting them does nothing.  The checkmark doesn't move, the menu title doesn't change, and the keyboard function doesn't change.

Additionally, the "Show/Hide input source name", "Show Emoji &amp; symbols", and "Show character viewer" menu options tend to just disappear from the menu and stay gone until reboot.

Any idea what would cause this, and/or how to fix?
I believe I have fixed it.  Based on some pages I found, I ended up deleting some prefs:

rm ~/Library/Preferences/ByHost/com.apple.HIToolbox*
rm ~/Library/Preferences/com.apple.HIToolbox*


After rebooting, the menu now acts normally.  If no other problems crop up soon, I'll mark this as answered.
