What's Wrong?

Description

In the Claude Code desktop app (Windows), the mouse scroll wheel is intercepted
and converted to arrow key presses that navigate through prompt history in the
input field, rather than scrolling the conversation panel.

A yellow status message in the bottom-right corner confirms this:
"Scroll wheel is sending arrow keys · use PgUp/PgDn to scroll"

Steps to Reproduce

1. Open Claude Code desktop app on Windows
2. Have an active conversation with several messages
3. Attempt to scroll up through the conversation using the mouse scroll wheel

## Expected Behavior

Mouse scroll wheel scrolls the conversation panel up/down.

Actual Behavior

Scroll wheel navigates through prompt history in the input field. The
conversation cannot be scrolled with the mouse wheel at all.

## Workaround

PgUp / PgDn keys work for scrolling. Clicking the conversation area or
scrollbar does not release focus from the input.

Workaround

PgUp / PgDn keys work for scrolling. Clicking the conversation area or
scrollbar does not release focus from the input.

## Request

Please add a setting to disable the scroll wheel → prompt history behavior,
or make the scroll wheel scroll the conversation when the cursor is hovering
over it (rather than over the input field).

## Environment

• OS: Windows 11 Pro
• Claude Code: Desktop app
• Model: claude-sonnet-4-6
