What's Wrong?

Keyboard arrow key scrolling through Claude responses stopped working in the desktop app (Windows 11) as of April 14, 2026. Previously I could scroll through responses using arrow keys, now it no longer responds to them.
I am on a laptop, no mouse, so not being able to scroll with the keyboard arrows is super inconvenient as I have some very long Claude responses

What Should Happen?

Arrow keys should scroll Claude responses.
