What's Wrong?

I cannot create an incognito chat. Clicking the "ghost" icon in the upper right corner _minimizes_ the window, rather than creating an incognito chat window. I'm using Claude for Windows Version 1.5354.0 (9a9e3d) in a Windows 11 Pro Lenovo laptop with the latest updates. I've performed all the recommendations from the Fin AI agent, the behavior persists.

What Should Happen?

Claude should provide a patch or version that fixes the problem. Incognito chats are an important feature for privacy.

Screenshot provided - note upper right corner only has minimize icon. Sometimes the "dash" minimize icon appears as a "ghost," but the behavior when clicked is to minimize the screen.
