What version of the Codex App are you using (From “About Codex” dialog)?
26.304.1528.0
What subscription do you have?
Plus
What platform is your computer?
Microsoft Windows NT 10.0.26200.0 x64
What issue are you seeing?
The app freezes if it's not in focus.
What steps can reproduce the bug?
Whenever you send a message and it's thinking, if you leave the app/hide it/minimize it (whatever), there's a 99.9% chance if you open it back it will be frozen and require a termination through Task Manager. If you stay inside the app while it finishes responding, it doesn't happen.
What is the expected behavior?

Thanks for the bug report. This is the first we've heard of this problem.
Based on the symptom, I'm guessing that the problem is related to notifications. By default, the app will notify you when it's done with a task, but it does this only if the Window is not in focus. Can you try disabling notifications in the "General" settings panel and see if the problem goes away?
Disabling notifications seems to have fixed it for now!
Also forgot to mention - When I first installed the app, I used to get notifications when it wasn't in focus (default setting), but ever since this issue started I know realize I don't get any notifications since the app becomes frozen. When I force kill it and relaunch it, it's as if the app didn't freeze (the response from the model is there rather than having to submit my message again)
OK, thanks for the confirmation. That validates my theory and gives us a good place to look for the root cause.
Two small bug additions - I'm on the Plus plan but the app still seems to think I'm not so it shows "Get Plus" button

and 2) the button to see limits sometimes shows and works and sometimes doesn't. On the occasions that I can check my limit, after checking if I click anywhere else in the app (to hide the pop-up with limits) - that "Local" button becomes just plain non-clickable/hoverable text
