Chat bugs when opened in new window

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When I open the Cursor chat in a window and then drag this window to my second monitor, the chat box does not work initially. I always have to then create a new chat and select the chat I was already on for that instance of the chat to work.

Steps to recreate:

  • Open chat as editor
  • Move that editor tab to another monitor
  • Chat becomes unusable

It it so frustrating as having the chat on a separate monitor is super handy. Please fix this!

Steps to Reproduce

Steps to recreate:

  • Open chat as editor
  • Move that editor tab to another monitor
  • Chat becomes unusable

Expected Behavior

Chat does not work after the steps I’ve described. When you type, nothing appears.
