Does this stop you from using Cursor
No - Cursor works, but with this issue
Thanks for reporting this.
A few things to try that have helped others with similar symptoms:
-
Clear Editor History: Press Cmd+Shift+P, type Clear Editor History, and run it. Then restart Cursor. This clears out any corrupted conversation state that can cause the panel to freeze.
-
Check your Max Tab Count: Go to Cursor Settings, search for Max Tab Count. If it’s set to 1, increase it to 2 or higher. A known bug causes agent panel crashes at that setting.
-
Full quit and relaunch: Fully quit Cursor (not just close the window) and relaunch.
If the issue persists after those steps, could you grab the following so we can narrow it down further?
-
Open Help > Toggle Developer Tools, click the Console tab, then reproduce the freeze. Check for any red error messages and share a screenshot.
-
Does the freeze happen with every new conversation, or only when opening specific existing ones?
Hey there!
Thanks a lot for your response. The issue has already been solved by myself. I believe there is some cache left after some sessions. That’s why it’s stuck for a while.I believe there is some cache left after some sessions. That’s why it’s stuck for a while.
