If codex is in the process of printing out it's final summary and you at that very moment hit return on a long prompt, it just sits there in limbo - you cannot quit, it won't respond, it allows you to type more and enter more prompts but it does nothing - forever lost. You need to then /quit and codex resume ... to get it back to where it was.
What steps can reproduce the bug?
- Make sure Steer is on
- Give it some work
- When it's giving you it's final work
summary... make sure you've entered a prompt and then immediately hitreturnwhile it's in the middle of printing it (and hasn't finished its final summary, still streaming - Bingo - locked up. Codex can no longer recover.
Reproducible 100% of the times.

@etraut-openai this is still happening and 100% reproducible in v0.105.0-alpha.10
@guidedways, we haven't had a chance to look at this yet. You're the only one who has reported it so far. Since you seem to be able to repro the problem, if you'd like to dig into it and try to find the root cause, that would be helpful. I'm not asking for a PR, but a concise description of the problem — a prompt that we can use to ask Codex to fix it.
Thanks. I think I've seen someone else report something similar but they're confusing this with a (now fixed) bug with steering. Having said that, would love to look into this and report back.
