using this code:

Loop
{
    WinWait, Untitled - Notepad
    WinClose, Untitled - Notepad
}

I want to keep any new notepad windows closed automatically.

And then I want to add a keyboard shortcut to exit AHK script: Esc::ExitApp

but when I add Esc::ExitApp the loop seems not working and notepad windows will not be closed automatically while code is still running:

Esc::ExitApp  ; ==> this line causing the loop to malfunction and not work as expected

Loop
{
    WinWait, Untitled - Notepad
    WinClose, Untitled - Notepad
}

Why this is happening and how can I make it work as expected?!
