resetting the pm6 preferences solved the “swallowing keys” for me on windows 10, dell xps 15, 6core, 32gb ram, 2tb ssd, german keyboard.
i exported the old preferences before that and i will reimport them step by step to figure out what caused the key swallowing.
when i imported the preferences all at once, the swallowing was back.
step by step reimport is a very annoying process, but at least i can rate pictures again as i used to.
