What's Wrong?

Version: 2.1.32

not model-specific

Description:

When using the AskUserQuestion tool
with a select list, pressing
Return/Enter to select the focused
option works intermittently — it
functions correctly in some sessions
but fails in others within the same
project. When it fails, the focused
option does not get selected on
keypress and requires mouse click
instead.

Expected behavior: Return key
consistently selects the currently
focused option in the
AskUserQuestion select list.

Actual behavior: Return key
selection works in some sessions but
silently stops working in others.
No error output. Mouse click still
works as a workaround.

Environment:

• macOS (Darwin 24.6.0)
• Claude Code (include version from

claude --version)

• Trigger: Stop hook presenting

AskUserQuestion via systemMessage

What Should Happen?

Pressing Return/Enter on a focused
option in the AskUserQuestion select
list should always select it.
Currently it works intermittently —
sometimes Return registers the
selection, sometimes it doesn't,
with no change in setup between
sessions.
