Interesting. I made a master in computer psychology.  It is an exact science but it depends on what school you believe on.

if you use linux, you know that there is the possibility that a binary designed for Ubuntu Linux may not work for another Linux distribution, but if you use Windows you would hopefully expect a Windows program to work the same way on all computers running Windows, or at least on the same version of Windows. but when this does not happen, you are quite doubtful about the exactitude of the (windows) computer science...

https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-setlayeredwindowattributes I assume when you make alpha channel not 0 it will catch the click.

This works "better" although I do not understand exactly what you should tweak to get it working

_WinAPI_SetLayeredWindowAttributes($hGUI, 0, 100,2)

Nope, win7 and win10 both clicks are going thru...

Thanks to @junkew, even using that winapi call, the end result is not always the same, it behaves differently if used in win7 or in win10 (at least on my PCs).
I continue this in my previous topic (https://www.autoitscript.com/forum/topic/197733-problems-on-appearance-transparency-and-dragging-of-a-gui) so as not to further hijack the OP subject.
