Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, this is a known bug. The browser tab breaks when you move it into a separate window. Crashes, unresponsive interactions, and broken element selection are all part of the same issue.

There’s an existing thread tracking this: Browser tab unresponsive after moving to new window (v2.4.22)

The team’s aware. No ETA yet, but your report helps with prioritization.

Workarounds for now:

• Keep the browser tab inside the main Cursor window, don’t use “Move into New Window”
• Use an external browser for dev tools or inspect element

Let me know if you have any questions.
