Harmonica, thanks for you videos, I found the reason that is causing this issue.
It seems Aurora switches focus to a table at the moment a time bank button is clicked, if chat is not minimized.
I'm not sure if I can prevent this, and I don't think you want to turn off the Auto time bank option.
So I would suggest that you keep the chat minimized. You can use Options / Auto hide chat, and also use StarsCaption Note editor to edit text notes. You can see
here how it works.
You can open it by double click and close it by just clicking on a table:
