Hey, thanks for the report. I see you’ve created three reports about the same issue. The main thread is here: Bug: Browser tab unresponsive after moving to new window (v2.4.22)
There’s already a workaround there, and the team is aware of the bug. In short:
Workaround:
- Keep the Browser tab in the main Cursor window (don’t use “Move into new window”)
- Or open localhost:3000 in a regular browser
Status: The bug is logged, but there’s no ETA for a fix yet. If there are updates, we’ll post them in the main thread.
I’m closing this thread as a duplicate. Please continue the discussion there if needed.
