What's Wrong?

On Windows 11, the full Claude Desktop main window (Cowork/Home view, not Quick Entry) disappears completely whenever I click on any other application, including apps on a different monitor and Snip & Sketch launched from the taskbar.

• The window is not minimised to the taskbar; it is fully hidden.
• The only way to get it back is to relaunch Claude from the Start menu. It then reappears in its previous position, so the process is still running.
• Happens with the window both maximised and restored.
• Multi-monitor setup.

Possibly related to #92933, but here the trigger is consistent: any loss of focus.

What Should Happen?

The window should behave like a normal window: stay visible (or go behind other windows) when another app or monitor gets focus, so users can take screenshots or work side by side with other apps.

Steps to Reproduce

1. Open Claude Desktop for Windows from the Start menu (full main window).
2. On a multi-monitor setup, click any other app (e.g. a browser on the second monitor), or click the Snip & Sketch icon on the taskbar.
3. The Claude window disappears completely and can't be restored from the taskbar.
4. Relaunch from the Start menu: the window reappears in its previous position.
