Does this stop you from using Cursor

Hey, thanks for the detailed report. Just to be clear, we don’t have a feature that auto-closes the Agents panel when you click a file, so this is definitely unintended behavior.

A couple things to check:

  1. Update Cursor to the latest version. You’re on 3.8.23, and we fixed a few right sidebar visibility glitches after that. Your case might already be covered.

  2. The diagnostics show Layout: editor, which suggests the Agents chat is opened as an editor tab, not docked in the right sidebar. If that’s the case, a single click on a file in the Explorer can reuse the preview tab and replace the chat tab, which looks like it “closed”. Workaround: pin the chat tab right click the tab > Pin, or disable preview editors by setting workbench.editor.enablePreview to false. Panel toggle is Cmd+Alt+B.

If it still happens after updating, please share a short screencast showing the panel closing so we can file an accurate bug. Let me know how it goes.
