Hey, thanks for the detailed report. I’ll go through it point by point. These look like two separate issues.
- Freezing when copying a large message
“Message is too long to display” appears only for very large messages. Clicking the message opens the full text in an editable field. Selecting or copying that much text there may freeze the window, which sounds like what you’re seeing.
To get the text without freezing the window, don’t click the message. Open the “…” menu at the top of the chat panel and choose “Export Chat as Markdown”. This saves the full chat, including your complete message, as an .md file you can open in any editor.
For future large hand-off reports, it may be easier to save the report as a file in your project and mention it with @ in the chat. The agent can still read it, and the chat stays responsive.
To help me pass this on to the team, could you try these steps and tell me what happens?
- Restart Cursor and open a new chat.
- Paste the large report and send it.
- Check that “Message is too long to display” appears.
- Click the message once.
- Press
Ctrl+A, thenCtrl+C.
Does the window freeze after step 4 or step 5? About how long does it stay frozen? And roughly how large is the report in characters or lines?
- Slash commands when editing an older message
This is a separate known issue that we’re already tracking. I can’t give you an ETA yet. To keep it separate from the freezing issue, please start a separate thread for it or join the existing one: Chat regression: can’t add skills when editing old messages; old messages lose blue links / orange skills
Let me know how the steps for issue 1 go.
