What's Wrong?

The main Claude Desktop window on Windows stays pinned above all other application windows. It does not behave like a standard window — when switching focus to another app, Claude remains visible on top instead of moving behind it.

What Should Happen?

Expected behavior

Claude Desktop should behave like a standard Windows/Electron window and follow normal z-order — it should be painted behind whichever window currently has focus.

Additional Information

This is a Claude Desktop app bug, not Claude Code CLI. The main chat window on Windows stays always-on-top of other applications and doesn't drop behind them when focus switches to another app. There's no in-app setting to disable this. Minimizing the window is the only workaround; quitting and relaunching does not fix it.
