claude-code - 💡(How to fix) Fix [BUG] Menu buttons close on mouseUp instead of registering click — Claude Desktop AND claude.ai web (Safari + Chrome)

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?

Every clickable menu in Claude opens on mouseDown but closes the instant the mouse button is released. Menus are only visible while the button is held down — single clicks do not register as discrete clicks, and the menu never persists open after release.

Affects BOTH Claude Desktop AND claude.ai web. Confirmed in Safari (incognito) and Chrome on the same machine. Indicates a shared frontend bug, not Electron-specific and not browser-specific.

Affected menus (all confirmed):

• Code tab mode picker (Plan / Edit / etc) — desktop
• Views menu (top-right of Code tab — background tasks, plan files toggle) — desktop
• Chat model picker — desktop
• Chat + attachments / connectors menu — desktop AND web
• User menu — desktop AND web
• Chat session name menu — desktop
• New chat + menu — web

Affects 100% of menu interactions. Workaround is click-and-hold, drag to target item, release.

Scope: Anthropic surfaces only. Finder menus, Safari dropdowns, System Settings, all other macOS apps, and all other websites respond normally to single clicks.

Regression: bug not present in 1.7196.0 (12 May 2026). First observed in the version installed prior to yesterday, persists in current 1.8089.1.

What Should Happen?

A single click opens the menu and it stays open until an item is selected or the user clicks away (standard click behaviour, matching every other macOS app and website).

Error Messages/Logs

No obvious errors at click time in ~/Library/Logs/Claude/main.log. Browser consoles not yet inspected — can provide on request.

Steps to Reproduce

Desktop:

1. Launch Claude Desktop 1.8089.1 (b98a06) on macOS Sequoia 15.7.7.
2. Single-click any menu (e.g. Code tab mode picker, Views menu top-right).
3. Menu flashes open and closes on mouseUp.

Web — Safari incognito:

1. Open claude.ai in Safari Private Browsing.
2. Single-click user menu or new chat + menu.
3. Same behaviour.

Web — Chrome:

1. Open claude.ai in Chrome.
2. Single-click user menu or new chat + menu.
3. Same behaviour.

100% reproducible across all menus on all three surfaces, every session.

What I've ruled out:

• Logi Options+: not running (Activity Monitor confirmed).
• Claude Desktop local app state: cleared ~/Library/Application Support/Claude and ~/Library/Caches/Claude, signed in fresh — persists.
• System-wide input issue: every non-Anthropic app and website is unaffected.
• Third-party input drivers: no Karabiner, BetterMouse, or similar utilities installed.
• Browser extensions: confirmed via Safari incognito (extensions disabled).
• Single-browser issue: reproduces in both Safari and Chrome.

Additional Information

Hardware: Mac mini M4 Pro, 24 GB RAM. macOS: Sequoia 15.7.7 (24G720) — stable channel, not beta. Browsers tested: Safari 26.5 (regular window and Private Browsing) and Chrome 148.0.7778.178 (Official Build) (arm64) — both reproduce.

This appears to be a shared React/web frontend bug affecting both Claude Desktop (Electron) and claude.ai web — likely a pointer-event handler regression in shared menu/dropdown components.

Impact: every menu interaction requires non-standard press-and-hold gesture across all Anthropic surfaces. Significantly slows agentic Claude Code workflows where mode switching and Views toggling are frequent.

Cross-filed with Anthropic Support for tracking.
