Paste Glitch in Cursor

[marzbanalex]

Describe the Bug

When using a jupyter notebook in python and the chat on the right of the screen, pasting into the chat just adds a new cell and won’t actually paste.

Steps to Reproduce

I’m using a m3 macbook pro 13 inch with Sequoia 15.5 . Im using o3 as the model and after sometime of chatting and using my notebook, sometimes the paste will stop working. I’m triyng to copy cell output and paste it into the chat. Even if I paste the chat into a search bar to remove formatting and then into that this still occurs. This happens after using the notebook for 1-2 hrs plus and then it starts doing this.

Expected Behavior

Paste into the chat.

It’s broken for quite some time.
Seems like nobody from cursor is very willing to fix that.

Jupyter Notebook Output Copy-Paste Not Working Correctly in Chat Panel

When using Cursor IDE with Jupyter Notebook, I’m experiencing a strange clipboard behavior: I copy the output of a notebook cell (not the input code, just the output). I then try to paste it directly into the Chat panel (AI assistant). However, nothing appears in the Chat input box. Instead, Cursor inserts a duplicate of the notebook cell’s input code directly below the original cell’s output — as if the cell itself was duplicated. If I copy the output and then navigate to another file or tab …
