Does this stop you from using Cursor

Hey, thanks for the report.

This is a known issue. If you close a chat tab without explicitly accepting the changes, Cursor may revert them. A fix was implemented recently, but you’re on a pre-release build (2.3.0-pre.15), so it might not be included yet.

Could you confirm:

1. Did you click “Accept All” (the checkmark button) in the Review panel before closing the chat tab?
2. If yes, could you share a Request ID from one of those sessions? (Chat top-right menu > Copy Request ID)

If you explicitly accepted the changes and committed them, but they still reverted, that’s likely a different bug we should investigate further.
