Product: Codex app for Windows Version: 26.406.3494 Plan: ChatGPT Plus (Codex included) OS: Windows 11 IDE: Cursor 3.0.16 Mode: Local

In a new Local-mode thread, the “Open in Cursor” button appears in the top-right initially, but disappears immediately after sending the first message.

Steps to reproduce:

Open the Codex app on Windows

Start a new thread in Local mode

Confirm “Open in Cursor” is visible in the top-right

Send any message

Observe the “Open in Cursor” button disappears

Expected result: “Open in Cursor” remains available after the first message so the thread/workspace can be opened in Cursor at any time.

Actual result: The “Open in Cursor” button disappears right after sending the first prompt and does not return.

Frequency / Repro rate: 100% reproducible (every time)

Troubleshooting attempted:

Windows app Repair performed (no change)

Attachments:

Screenshots showing button present before first message and missing after first message

extent analysis

TL;DR

The "Open in Cursor" button disappearance after sending the first message in Local mode can be addressed by investigating the Codex app's UI update logic.

Guidance

  • Verify if the issue persists when using a different IDE or mode to isolate the problem.
  • Check the Codex app's settings or preferences for any options related to the "Open in Cursor" button's behavior.
  • Investigate potential UI update issues in the Codex app, such as incorrect state management or event handling, that might cause the button to disappear.
  • Consider testing with a different version of the Codex app or Cursor IDE to see if the issue is specific to the current versions.

Notes

The provided information suggests a reproducible issue, but without access to the Codex app's codebase or more detailed debugging information, it's challenging to provide a definitive fix.

Recommendation

Apply workaround: Modify the Codex app's UI update logic or settings to prevent the "Open in Cursor" button from disappearing after sending the first message, as the root cause is likely related to the app's internal state management.
