Describe the Bug

Whenever I am actively looking at a large file It doesn’t allow me to send the message to cursor even when active tabs is removed from the context.

Steps to Reproduce

I have a file that is about 1 GB large and whenever I am looking at that file (when it is my active tab) it doesn’t allow me to send a message to cursor. As soon as i click off of it i can send the message. I don’t have to exit the tab i just need to select another tab for it to send.

Expected Behavior

It should just be able to send because the large file isn’t in the context of cursor

Operating System

MacOS

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. Yes, even though the file is missing in the context, the chat sees it and throws an error. We’ll try to fix this in a future release.
