What's Wrong?

Claude Version: 2.0.9 (Claude Code)
Mac Uname -a: Darwin Richards-MacBook-Pro.local 23.6.0 Darwin Kernel Version 23.6.0: Mon Jul 29 21:13:04 PDT 2024; root:xnu-10063.141.2~1/RELEASE_ARM64_T6020 arm64

Claude code, at some point, starts capturing all the mouse movement as text in the edit box. I didn't do anything special, and I can't pinpoint what triggers it. It just happens after about an hour - that's the best correlation I have. Stopping and restarting claude code fixes it. Claude will still be able to interpret some commands, recognizing that "the user seems to have sent some screen control codes by accident"

I'm just using the standard mac terminal.

What Should Happen?

Anthropic should protect the claude prompt box from mouse input.
