Cursor Terminal detects KeyboardInterrupt from other terminals

[user579 (B)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

On Windows, sometimes if a powershell terminal has a KeyboardInterrupt exception (Python) and it’s waiting on Terminate batch job (Y/N) the cursor terminal will also hit KeyboardInterrupt until the powershell terminal gets a response.

Steps to Reproduce

Run pytests in the powershell terminal abort early with ctrl+c, instruct the agent to also run pytests.

Expected Behavior

The cursor terminal should not hit KeyboardInterrupt when there is no new instance of ctrl+c.

Operating System

Windows 10/11

Additional Information

Additionally sometimes I’ll see C^ when Cursor? is trying to close a terminal? This might have something to do with the issue, it has a hard time detecting end of output and will often times wait for the user to press enter a few times. That is probably the most nuisance issue when using cursor btw.

Does this stop you from using Cursor

No - Cursor works, but with this issue

If you really want to fix issues consider having a bug report option from within cursor to accurately submit the error state.

Hey, thanks for the report. Could you let me know which model you’re using? Also, could you share the request ID? For this, you need to disable privacy mode if it’s enabled, then reproduce the issue when it happens again and copy the ID.
