Hey, thanks for the report. There’s a known issue with copying text from some UI components in Cursor 2.0, especially in Plan mode (it’s being tracked).
To help diagnose, please clarify:
Where does it happen? Are you using the Agent in the sidebar or opening it as an Agents Window?
Does it work in Ask mode? Can you copy from regular Chat/Ask responses, or is it only broken in Agent mode?
Screenshot: could you share what you see when you try to select text?
Also, please test with extensions disabled to rule out conflicts: cursor --disable-extensions.
Seeing this same behaviour in both sidebar and agent mode on MacOS. Clicking the copy to clipboard button works but highlighting and copy does not. Cheers.
