  • I am using the latest version of Claude Code

What's Wrong?

Since upgrading to v2.1.78 on Windows, text selection in the Claude Code desktop chat interface is broken.

Behavior before v2.1.78: I could click and drag to select any portion of text in a chat message, then copy it normally with Ctrl+C.

Behavior in v2.1.78: When I try to select a portion of text inside a chat message, the entire message block gets selected instead of just the highlighted portion. This makes it impossible to copy a specific part of a response.

This regression appeared after the automatic update to v2.1.78 tonight. The previous version (v2.1.77) worked correctly.

What Should Happen?

Clicking and dragging over text should select only the highlighted portion, allowing the user to copy just that specific text with Ctrl+C — exactly as it worked in v2.1.77 and earlier.

Error Messages/Logs

Steps to Reproduce

  1. Open Claude Code desktop app (v2.1.78) on Windows 10
  2. Start a new chat and get any response from Claude
  3. Try to click and drag to select a specific word or phrase within the response
  4. Observe that the entire message block gets selected instead of just the dragged portion
  5. Try Ctrl+C — it copies the entire message, not the intended selection

extent analysis

TL;DR

The most likely fix for the broken text selection in the Claude Code desktop chat interface is to revert to version 2.1.77 until the issue is resolved in a future update.

Guidance

  • Verify that the issue is indeed specific to version 2.1.78 by checking if other users have reported similar problems.
  • Try resetting the application settings to their default values to see if the issue persists.
  • Consider reaching out to the development team to report the regression and ask for a patch or a workaround.
  • As a temporary workaround, continue using version 2.1.77 or explore alternative methods for copying text, such as using the web or CLI versions of Claude Code.

Notes

The issue seems to be a regression introduced in version 2.1.78, and reverting to the previous version may be the most straightforward solution until the problem is fixed.

Recommendation

Apply workaround: Revert to version 2.1.77 or disable auto-updates until a fixed version is released, as the current version introduces a significant usability issue.
