For some reason the typewriter node seems to only pull input from a focused window when the renderer window is dx9. It works fine when I use a dx11 renderer and a global keyboard input node, but the Keyboard (window) node only works with Typewriter and dx9.
Unless it’s just a quirk with my system, the bug should be repeatable by opening the Typewriter help patch and adding a dx11 text and renderer node. You can click on the dx9 window and add text, but clicking on the dx11 window doesn’t work. Doesn’t seem to be a problem with the Keyboard (window) node either, it still generates output either way. Something seems to be specifically amiss with the typewriter node here.
