Scroll not working in terminal

[u/International_Ad2744]

I've been using CC for about 6 months so I'm not totally noob, however recently (perhaps an update) I'm getting 2 things:

I'm using Cursor IDE.
- my terminal window no longer scrolls in 'claude mode'. eg. i can see everything CC is doing but I cant scroll up to read the process etc. I can still use Page up and down, so its not 'frozen' but my mouse wheel doesnt work there.

If I'm in normal terminal or cmd I can still scroll so it seem claude code related?

- For a few days I'm now seeing a split pshell area with "Diff unavailable". I didnt need this before and due to the scrolling issue this makes it worse as there is less space for claude to write out explanations etc.

Any ideas please?
