Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
Chat on a new window is really bugged:
When I try to attach a code or file it closes immediately.
The Custom Agent selection UI seems odd (it shoots up).
I can’t select previous chats without resetting the chat.
Trying to “Ctrl+L” to go to the chat closes it.
Steps to Reproduce
- Open a new chat as Editor
- Drag the chat to another screen or outside of Cursor
- Resize the chat to be full screnn
-
Try to attach a code block
– On a file, select a the code and press the “Add to Chat” Keybind (not clicking it) -
Try to select another Custom Mode on a previous chat, the selector will appear on the top, not on the Agent.
-
On a previous chat (already with conversation), try to select another chat on the Chat History (top right), clicking will do nothing.
-
Trying to use the Go to Chat keybind closes the chat, when it opens again it appears on the sidebar.
Expected Behavior
The chat on a screen outside of Cursor is really handy sometimes, you can see more and it occupies less space on the actual editor.
I should be able to fully use the chat on another screen, all the features and keybinds should work fine.

Additional Information
On clicking to go to a previous chat, on the console (Developer tools) there is an error occuring:
Uncaught TypeError: Cannot read properties of undefined (reading ‘shiftKey’)
at Object.onClick (workbench.desktop.main.js:4823:8345)
at HTMLDivElement. (workbench.desktop.main.js:1544:15251)

Does this stop you from using Cursor
No - Cursor works, but with this issue
