Every time i change my input language to type in After Effects ( i.e. from English to Thai ) with Grave Accent key.
It's keep freezing and become Not Responding.
But when i change my input language by change it in Taskbar icon. Everything was fine.
It's never happen in CC or CC2015. !
sorry for my language.
The solution: use an earlier version of After Effects. You can get one if you do not have one. The newest version broke many things that always worked before.
Did you ever solve this issue? Did Dave's advice assist you?
