The Wails systray runs the left-click handler synchronously inside the tray window procedure, and creating a window on a running app pumps a nested Win32 message loop while WebView2 initialises. ensureWindow held the non-reentrant createMu across that creation, so the second button-up of a double click re-entered ShowWindow from the pump and blocked the main thread on its own lock. A goroutine holding createMu while the main thread pumped, and the Open* dialogs holding mu across NewWithOptions, Show, Hide and InvokeSync, exposed the same inversion. WindowManager now serialises creation with a per-slot creating flag and queues the callers' operations until the window exists, and no Wails call runs while mu is held. The tray click and second-instance handlers call ShowWindow off the message loop.
