Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report.

We need a few more details to reproduce:

  • Which mode does this happen in: Ask, Agent, or Plan
  • Exact steps: what you click, where you start typing, and when the Stop button disappears
  • A screenshot or a short screen recording
  • Open Help > Toggle Developer Tools and share Console errors from the moment the button disappears
  • If it’s tied to a specific AI request, please include the Request ID: chat menu (top right) > Copy Request ID

Please also check if it reproduces:

  • After a full restart of Cursor
  • With extensions disabled: run cursor --disable-extensions from the terminal

Share the details and I’ll pass them to the team if needed.

I think we misunderstand. The button changes state often:

  • nothing going on, mic button. I type a letter, it gets send button
  • prompt running, stop button. I type a letter, it gets send button

Any mode.

Problem is that after typing this letter, I cannot stop agent/ask/plan anymore when I see it going the wrong way.

Hint: In Antigravity it stays a Stop button, and I can still queue a new prompt by hitting enter. Sensible simple solution IMO.

Cursors UI is slowly getting really good and consistent, BTW.
