Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey @mwjt42

I had trouble reproducing this last night, and then I arrived to a very warm laptop this morning and a lot of windows open. So there’s definitely something not right. Following up on this.

@mwjt42 , out of curiosity, does this happen when you click “Connect” button in Cursor, or when the server has already connected? Any chance this happens around the time that your computer restarts, or was just booted up? Additionally, do you have more than one workspace/more than one window of Cursor open?

I just open Cursor and then the calls begin. I’ve previously connected and authorised Neon.
