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.
