Поток для определения языка или изменения Caps Lock срабатывает только в первый раз ⇐ Python

[Anonymous]

Я пытаюсь создать программу, которая выдает объявление всякий раз, когда вы меняете язык на клавиатуре или меняете регистр.
У меня проблема в том, что она объявляет в запускается, а затем всякий раз, когда я меняю язык или нажимаю клавишу Caps Lock, сообщение больше не появляется.
Буду признателен за любую помощь или информацию.
