When I have a Jupyter notebook with a cell copied and then try to copy and past separate text into the chat window, the jupyter notebook page seems to take over the paste command and pastes the old cell into the notebook.
The text isn’t pasted into the chat window. I can select a different type of window and it will work. Also pressing Cmd-Shift-V works
Steps to Reproduce
Open a Jupyter Notebook copy and paste a notebook cell, then select other text and attempt to paste it in the chat sidebar while the notebook is open
Expected Behavior
Sidebar window should capture the paste command if it is clicked on and focused

When I cut and paste from anywhere in Cursor while have a Jupyter notebook open I create a new cell in the open Jupyter Notebook. I can’t cut and paste from terminal, from other files, or from the notebook into chat.
Steps to Reproduce
Open an ipnyb file. Use cut and paste and click in chat. Try to paste into chat. A new cell is created.
You can cut and paste from within or between jupyter notebooks, but not outside of the notebook.
Expected Behavior
Can cut from a notebook and paste in a chat.

Whats more frustrating in my situtation, the cell in the notebook I had previously selected gets pasted with the same code cell every time, and I cannot undo that neither with CMD+Z nor with Edit → Undo.
I am experiencing this issue too. It doesn’t always happen, but once I start getting this problem, it doesn’t go away until I reload the editor. It’s pretty annoying. I’m on Windows so it’s not a macOS-only problem.
Same issue here. Almost happen every day when I open jupyter notebook in Cursor, very bothering. If I use Cmd + Shift + V, the cursor AI is unable to locate the specific code snippet I want to refer. Hope the cursor team can investigate and solve this problem at your earliest convenience.
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 inside Cursor before pasting, it works correctly and pastes the expected content into the Chat.
Restarting Cursor temporarily resolves the issue, but it reappears after some time of continued use.
