Application only closes after mouse movement following frontend interaction

[VdanielVPL]

Description

The application does not close when the window's close (X) button is clicked after interacting with the frontend. The app only closes if the mouse is moved after clicking the close button.

To Reproduce

1. Create a new Wails project with React and TypeScript: wails init -n myproject -t react-ts
2. Start the application.
3. In the frontend, click the Greet button.
4. Move the mouse over the close (X) button in the application window and click it without moving the mouse afterward.
5. Notice that the application does not close immediately. However, moving the mouse even 1 pixel causes the application to close.

Expected behaviour

The application should close immediately upon clicking the close (X) button, without requiring additional mouse movement.

Attempted Fixes

I tried several methods to fix this issue, but none have resolved the problem so far:

1. Listening to the wails:window:close event:

• I used runtime.EventsOn(ctx, "wails:window:close", func(optionalData ...interface{}) { runtime.Quit(ctx) }) in Go to handle the close event and call runtime.Quit(ctx) directly, but the issue persisted.
  Using OnBeforeClose and OnShutdown:

2. I attempted to clear the shutdown-related handlers by setting them to nil in the app struct. This included resetting any relevant fields related to shutdown processing, but the issue persisted.

3. I also commented out the front-end click handlers to check if any JavaScript was blocking the closure, but the behavior remained the same.

Thanks for reporting this. This was something that came up a couple of times before and sometimes it could be observed and other times not. I'll try and dig out the previous discussions around this.

I'm wondering if anyone else can confirm this.

Reproduced on an old-ish Win 10 machine I've got lying around and on a Windows 11 Surface Pro 9, but not on my Mac.

Maybe it's something specific to Windows?
