Additional Information

This is a new issue/regression in the last week. Has always worked before that I can remember.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi @yaakov_fg!

Thanks for the report.

Do you have Cursor’s built in browser open when this happens? This might match a known issue we’re already tracking.

I’m seeing what looks like a related 3.10.20 macOS chat keybinding/focus regression.

The VS Code command “View: Quick Open Previous Recently Used Editor in Group”
(workbench.action.quickOpenPreviousRecentlyUsedEditorInGroup) used to let me switch between chat/agent tabs when focus was in the chat/agent area, the same way it switches between code editor tabs.

Now, when I use that shortcut from the chat/agent area, it gets routed to the normal editor/code tab selection instead of switching between chat/agent tabs.

One thing to add – a key reason for choosing cursor above claude code or codex is that is has the best navigation / keyboard shortcuts so the actual dev experience is smooth, but this significantly hurts that advantage.

Repro:

  1. Open Cursor on macOS.
  2. Open multiple chat/agent tabs.
  3. Focus the chat/agent area.
  4. Trigger workbench.action.quickOpenPreviousRecentlyUsedEditorInGroup.
  5. Actual: Cursor selects/switches code editor tabs/windows.
  6. Expected: Cursor switches between chat/agent tabs as before.

This started within the past week after updating. It feels similar to the other 3.10.20 chat keybinding/focus regressions where chat shortcuts are not handled by chat and instead get intercepted by the IDE/editor.

I have not found a reliable workaround yet. Reload Window / full restart may temporarily help with some chat focus bugs, but it does not restore the old chat-switching behavior for me.

@Colin now that you mention it, yes, I did have the browser open, and when it is closed, I cant repro anymore
