Cursor IDE
Describe the Bug
After a recent cursor update, I’m having a super strange experience working with Jupyter notebooks.
When I have my agent working for me on the notebook and I go to another file to begin doing some parallel work while the agent completes its changes for me to review, it keeps forcibly switching me back to the notebook that the agent is modifying.
So, I will try to edit another file and it flashes on the screen to return me to the section of the notebook the agent is editing. It goes on like this and makes the editor mode practically unusable for me for Python Jupyter Notebooks. I don’t know if I had some of my default settings changed but I can’t figure out a way to get it back. This is NOT the behavior that occurs when I am editing standard files, and I don’t recall encountering this behavior before.
Steps to Reproduce
BUG:
- open jupyter notebook file and have your agent do some work on it
- open another python file and start editing it
- editor will switch you back to the notebook tab, interrupting your work
WORKS FINE:
- open python file A and have your agent do some work on it
- open another python file B and start editing it
- No interruptions, work on file A is done and you are fine to work on file B
Expected Behavior
I would expect the Python notebook to act just like any other file where I can dispatch the agent to work on it, and then I can go ahead and edit my other notebook or file in parallel and then come back to the notebook when I’m ready.
