We’re no longer able to open the subagent window or get any output from it (both conversation, thoughts, and response).

Meaning:

1. Subagent is invoked.

2. We cannot access its process:

3. Work is performed eventually, and main agent receives responses.

4. Nothing is showing on the Cursor output windows.

5. Happens for subagents created manually and using the task.

6. Happens with all models, also with “inherit”.

PSB my setup.

Your help is appreciated.

Hi @vaiden,

This is a known issue that our team is actively investigating. The subagent window click behavior broke in recent builds — the button renders but the click doesn’t navigate to the subagent’s conversation. Your observation that the work still completes in the background is consistent with what we’re seeing: it’s purely a UI issue, not a problem with the subagent execution itself.

A couple of things that might help in the meantime:

1. Reload Window (`Cmd+Shift+P` → “Developer: Reload Window”) — some users have found this temporarily restores the click behavior for the current session

2. If Reload Window doesn’t help, could you check the Developer Console (`Help > Toggle Developer Tools` → Console tab) for any red error messages when you click “Open”? That would help narrow down whether there’s a JavaScript error blocking the overlay

Also noting that you mentioned this happens in both the editor layout and the Agents window — that’s a useful data point for the fix.

You may also find [this related thread](https://forum.cursor.com/t/agent-execution-does-not-reflect-real-time-updates-in-ide/157032) helpful, which describes a similar pattern.

Thanks for the prompt reply.  
No error presented in dev tools upon clicking (both in editor and agents windows).

I don’t think it’s related but I do see this error in the logs (even without clicking):

```auto

Thanks for checking the Developer Console, @vaiden. The fact that **no errors appear on click** is actually a useful signal — it rules out a surface-level JS exception and points toward one of the deeper UI state issues the team is already tracking.

Regarding the `[composer] No first token received within 2s` warning — you’re right, that’s separate from the click issue. It relates to initial streaming latency and shouldn’t affect the subagent window behavior.

@Israel_Kovas - thanks for confirming this affects Windows as well. The team is actively working on a fix — the cross-platform confirmation helps scope it.

No action needed from either of you at this point. This will be resolved in an upcoming update.

Hey @Israel_Kovas!

This should be fixed in _v3.2.11_ – please upgrade and let us know if you face an issue (we’re still catching some corner cases).
