Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
I left the Agent on GPT-5-high for a while, and when I returned, I noticed an open working terminal. I tried opening it and closing it, but neither KeyboardInterrupt nor Q gave any result. When I killed the terminal, the Chat Agent was stuck in a state where it seemed to be continuing to work, but in fact it just froze.
When I finished the previous paragraph, “Connection failed” appeared and the chat aborted. See Additional Information.
Steps to Reproduce
Set the task to develop and debug a project on PyQt6

Does this stop you from using Cursor
No - Cursor works, but with this issue
