Fix / Workaround

Environment

  • Cowork desktop app: <!-- fill in via Claude menu → About -->
  • macOS: <!-- fill in -->
  • Mode: Dispatch, opened from inside the Code section of Cowork (the embedded variant). The standalone Dispatch — opened from the main Cowork section — is NOT affected.

Scope

  • Affects: Dispatch when opened from inside the Code section of Cowork — all assistant message bubbles, regardless of content type (plain text, blockquotes, lists, code blocks).
  • Does NOT affect: Dispatch opened from the main Cowork section (selection/copy works normally there); user's own message bubbles in either variant.

Workaround Asking the assistant to save content to a file on disk and reading it from there. Alternatively, opening Dispatch from the main Cowork section instead of from Code. Both are functional but high-friction for routine quoting / forwarding from a Code-section workflow.

Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

Environment

  • Cowork desktop app: <!-- fill in via Claude menu → About -->
  • macOS: <!-- fill in -->
  • Mode: Dispatch, opened from inside the Code section of Cowork (the embedded variant). The standalone Dispatch — opened from the main Cowork section — is NOT affected.

Actual Text in assistant message bubbles is not selectable. Selection gesture has no visible effect; ⌘C copies nothing; right-click does not show a "Copy" option.

Scope

  • Affects: Dispatch when opened from inside the Code section of Cowork — all assistant message bubbles, regardless of content type (plain text, blockquotes, lists, code blocks).
  • Does NOT affect: Dispatch opened from the main Cowork section (selection/copy works normally there); user's own message bubbles in either variant.

Workaround Asking the assistant to save content to a file on disk and reading it from there. Alternatively, opening Dispatch from the main Cowork section instead of from Code. Both are functional but high-friction for routine quoting / forwarding from a Code-section workflow.

Impact Routine copy operations from Dispatch-in-Code — quoting an answer into Slack, pasting a generated snippet into a doc, taking a fragment for further iteration — all require either an explicit "save to file" round-trip or context-switching to the standalone Dispatch.

Evidence Screenshots available on request.

What Should Happen?

Text inside assistant message bubbles is selectable and copyable, matching the behavior of Dispatch when opened from the main Cowork section, and matching other macOS chat apps.

Steps to Reproduce

  1. Open Cowork desktop on macOS.
  2. Navigate to the Code section.
  3. From inside the Code section, open Dispatch (the embedded Dispatch view).
  4. Have a conversation with the assistant; receive any reply.
  5. Try to select any text inside an assistant message bubble — by click-drag, triple-click, ⌘A, or right-click → Copy.

TL;DR

The issue can be temporarily worked around by opening Dispatch from the main Cowork section instead of from the Code section, allowing text selection and copying to function normally.

Guidance

  • Verify that the issue is specific to the embedded Dispatch view in the Code section by comparing its behavior to the standalone Dispatch view.
  • Check if there are any differences in the HTML or CSS structure of the message bubbles between the two Dispatch views that could be causing the selection issue.
  • Test if the problem persists across different types of content (plain text, blockquotes, lists, code blocks) to ensure it's not content-specific.
  • Consider inspecting the application's code or configuration to identify any potential differences in event handling or styling between the embedded and standalone Dispatch views.

Example

No specific code example can be provided without more information on the application's internal workings, but inspecting the DOM structure or CSS styles of the message bubbles might reveal clues.

Notes

The root cause of the issue is unclear without more technical details about the application's implementation. The workaround suggests a difference in how the embedded and standalone Dispatch views are handled, possibly due to different event listeners or CSS rules applied to the message bubbles.

Recommendation

Apply workaround: Open Dispatch from the main Cowork section when needing to copy text from assistant message bubbles, as this is a functional albeit high-friction solution until the root cause can be identified and addressed.
